We dialed up Alec Morefield from Slavens Racing for his or her enter on coping with the hydraulic clutch problem. Here’s his sage recommendation:

Due to the age of your motorbike, your grasp cylinder and/or slave cylinder more than likely have to be rebuilt. Bikes that sit and don’t get ridden typically or simply lengthy within the tooth sometimes require a rebuild equipment to repair your drawback. These kits include the mandatory seals and O-rings to correctly rebuild your grasp cylinder and slave cylinder. After utilizing a rebuild equipment, it would be best to comply with the identical bleeding process as acknowledged under. Before ordering a rebuild equipment, you may attempt the reverse bleeding process to make sure you don’t simply have air in your line.

Reverse bleeding the clutch line and clutch grasp cylinder is de facto an elementary process. Rekluse makes a clutch bleeding equipment that can correctly bleed your clutch. Before you begin this course of, be sure you have a bleeding equipment (just like the Rekluse unit) and the correct fluid. Most KTM, Husqvarna and GasGas fashions use brake fluid DOT 4 or 5.1, however some older KTMs take mineral oil. Simply take a look at the cap on high of your grasp cylinder and it’ll let you know what sort of fluid to make use of. If you’ve got aftermarket caps in your grasp cylinder, consult with your proprietor’s guide to make sure you use the correct fluid. Using the improper fluid will end in you having to switch/rebuild your grasp cylinder and slave cylinder.

Next, take away the cap, and we suggest wrapping the grasp cylinder with a store towel to soak up the brake fluid/mineral oil that can slosh out as soon as the method begins. To start reverse bleeding your clutch, it would be best to begin down on the slave cylinder. Before you hook the bleeder equipment (syringe and clear line) as much as the bleed screw on the slave cylinder, fill your syringe up with the correct fluid. Take the time to push out all of the air bubbles in your syringe. Once your syringe is stuffed, take away the rubber cap off the bleed screw on the slave cylinder. Then, earlier than hooking the syringe to the bleed screw, be sure you loosen the bleed screw. Next, put the syringe/line on the bleed screw and slowly push the fluid up from the slave by means of the clutch line and out the grasp cylinder. Keep pushing the fluid by means of and permit the towel to soak up the overflow of the fluid (or bucket to catch the fluid) till you now not see air bubbles within the grasp cylinder. You could have to work the lever slightly bit to see when you get anymore bubbles, and be sure you preserve stress on the syringe whereas doing so. If you’re getting some extra air bubbles, you may need to undergo this course of two or thrice. Once you now not have any air bubbles, tighten down the bleed screw on the slave cylinder and take away the syringe from the bleed screw. Now, you need to verify and see what your lever appears like; if it’s good, reinstall your cap in your grasp cylinder, and clear the grasp cylinder and slave cylinder off with a brake-parts cleaner. Now, you’re able to experience!

FAULTY FOAMER

Dear Mr. Know-It-All,

I’ve a six-year-old Husqvarna FE450, and it’s the greatest machine I’ve owned (and I’ve bought 23 machines through the years!), however my query has nothing to do with it. Because I’m a dual-sporter, I need to keep away from getting flats on lengthy rides. Carrying a tube and CO2 cartridges, together with a pack of instruments, is flat painful. I’ve been operating bib mousses with good outcomes till final weekend. They’re a ache to mount, and my final effort was the hardest but. I had a brand new Nitromousse and was sticking it in an IRC M5B. I needed to muscle it in, because the bead was so tight that I may barely get a tire iron in. I lastly rammed it on. We had an enormous experience arrange and trucked our bikes to the placement, acquired dressed, and I made it lower than 20 miles when the froth tube popped out of the tire and acquired rammed into the swingarm.

The tire seems good, because it was model new. This turned my day right into a nightmare! What occurred?

Harry, right here’s some sage recommendation about bib-mousse set up. First, make sure that your foam insert is the correct dimension to your tire. There is little question in my extremely organized mind bucket that both the insert was too huge or your tire was too small for the mousse. You really broke the bead on the tire throughout set up, and that is what let go in your experience. Once the bead is damaged, it can leap off the rim, and this let the foamer balloon out of its nest.

In the long run, be smarter than the tire. If you may’t preserve the bead dropped under the rim over the past 10 inches of the set up, and you employ an extended tire iron for leverage, you may snap the bead fairly simply. I exploit Motion Pro’s Bead Buddies (two is the minimal, whereas three to 4 retains the bead dropped under the rim correctly), take small bites with the tire iron and work slowly. Done correctly, and with the right-sized mousse, the duty is kind of pedestrian. Now, good luck, and we’re all relying on you!

GETTING LOW

Dear Mr. Know-It-All,

I’ve simply put a down fee on a brand new GasGas ES500. Will the suspension reducing linkage by AltRider match the GasGas? Are there different reducing choices? What will I have to do to the forks to degree it out? Price is an element. Please assist an outdated man who has been studying your recommendation for 40-plus years. Thank you.

If reducing simply the rear finish works for you, then the AltRider’s variableheight suspension reducing linkage can decrease your seat top to 4 completely different heights: 4.5mm (0.2 inches), 16mm (0.6 inches), 27mm (1 inch) or 38mm (1.5 inches) decrease than manufacturing unit top. I’ve a problem since each ends ought to be lowered equally in order that the steadiness of the machine stays integral. I questioned Dick Wilk, whom I belief with suspension counsel, and he works on the idea that the fork and shock work in unison so the machine’s spacers match internally to shorten the journey. Dick says that the majority go 1 to 2 inches, and each dampers may be introduced again to inventory with out a lot bother. He did say that the fork springs have to be shortened as effectively. The AltRider (www.altrider.comreducing linkage sells for $235, and the Dicks Racing (www.dicksracing.commodifications will set you again $495.

PROJECT BIKE SHOOTOUT: KTM 300TPI VS KTM 300TBI

Jeff Slavens, the owner of Slavens Racing, is an experienced off-road rider and is passionate about riding in Colorado. He owns two KTM 300 bikes, the 300XC-W TPI and the new 300XC TBI. In this article, he shares his experiences and modifications he made to these bikes for off-road riding in the high elevations of Colorado.

First, let’s talk about the KTM 300XC-W TPI. Jeff first rode this bike in stock form to establish a baseline for its performance. He found that the suspension and engine lacked stability and bottoming resistance when riding at higher speeds or in more aggressive terrain. The stock engine also lacked low-end grunt and midrange pull compared to carbureted models. To address these issues, Jeff made modifications to increase compression and correct the fueling. He installed a high-compression head and used a remapped ECU to improve the engine performance. He also upgraded the suspension with aftermarket components to improve comfort, stability, and bottoming resistance.

Now let’s talk about the KTM 300XC TBI. This bike has a new chassis and swingarm that offer improved rigidity. The new 300 TBI engine is powerful and torquey, but the power delivery is more aggressive compared to the XC-W model. The XC-W has a more compliant suspension and is better suited for trail riding, while the XC is stiffer and designed for racing. However, Jeff found that the stock suspension setup of the XC is not well suited for rocky and rooty trails in Colorado. He made modifications to the suspension to improve compliance, stability, and tracking.

In addition to these modifications, Jeff recommends several must-have items for both bikes. He suggests installing radiator guards for impact protection, SXS handguards for hand protection without limiting mobility, and various other protective guards for the bike’s components. He also recommends adding a cooling fan to keep the engine temperature in check during tight and technical trail riding. For better traction, he suggests using specific tire setups with Tubliss inserts to adjust air pressure according to the riding conditions. He also recommends upgrading the seat for better comfort and using stainless steel footpegs for a more comfortable and effective riding position. For longer rides, he suggests installing oversized fuel tanks.

In conclusion, Jeff prefers the XC-W model for its forgiveness, comfort, and manageable power delivery, especially in tight and technical terrain. He describes the XC as intense and more suitable for experienced riders who want an aggressive and thrilling riding experience. Both bikes can be significantly improved with modifications to the engine, suspension, and protective components.
