I run X ring chains and they last forever. They are not as wide as o-ring. V-mar makes a nice wide chain guide. A little trimming can make a standard guide work also. On my Rev 3, I had to put the master link clip towards the inside to avoid it touching the brake pedal http://www.vmar.com/chain-guide.html

Galfer pads feel the same. The Jitsie race pads are marked Goldfren on the back. I tried putting putting a 2008 Rev 3 rear wheel on my Evo. The disk is a little bigger, 3/16" or maybe 1/4" bigger in diameter. I could get the axle in but the disk drags on the caliper. I could not see if the Evo pads could take advantage of the larger disk. See the comparison pictures. Rev 3 pad also have more area.

DS80. Newer models are called JR80. They have a solid reliability reputation. http://www.suzukicycles.org/DS-series/DS80.shtml

Dan - Are you saying the jump comes after the throttle burst? I'm trying to do it at the same time. Actually, I'm trying to compress the front wheel on the obstacle, hit the throttle and jump all at the seem time. Although, there are a number of things that have to happen in a short time period so what I'm actually doing may be somewhat different.

I see that some riders can get a very quick almost explosive jump up from the pegs when unloading. When I attempt, it feels kind of slow and mostly like I'm compressing the rear suspension rather than pushing my body up quickly. Does this imply that my timing is off...maybe too early? I get some lift but not as much as I would like. I'm 155 lbs if that makes a difference.

Beta USA does list a 2017 improvement as: New rear brake pump: provides a more powerful yet progressive rear brake feel. Did they change bore size or just brands?

Who sells Goldfren S33 and is in or ships to the US?

Fluid has been flushed and pads are new. Original pads felt the same. A friend with a 2016 beta has the same rear disk and also complains the brake is weaker than his gas gas

I have a 2014 factory model beta. The rear brake has always seemed weak. I got a ride today on a 2017 factory model and the brake felt much much better....much stronger yet just as easy to control. Visually, the main difference is the NG brake disk which has less cut out area so more friction area. Has anyone tried installing the NG disk on a 2014 or anything else to improve brake power? The other difference I noticed was that the metal backing plate of the pads was sort of a bright brass colour. Mine are sort of a dull colour. I think they mine are the Jitsi race pads but the originals felt much the same.

My seat of the pants guess or maybe soles of the boots guess is that trials bikes max out around 6000 rpm, maybe less. That is why they feel "softer" with lower gearing...if it gets away from you, it runs out of rpms fairly quickly.

The sprocket spacer is 0.326 inches. It has a step to center on the wheel and another step to center the sprocket. Extra wheel spacer on the sprocket side is 0.233". The disk spacer is 0.198". It has a counter bore on the wheel side because the GG wheel has a little step on that side. Extra wheel spacer on the disk side is 0.147".

Do you just want thickness or detailed drawings?

I answered my own question. The GG wheel can fit a Beta but it takes 4 spacers, disk spacer, sprocket spacer plus right and left wheel spacers. This is an '04 or so GG wheel on a 2008 Rev3. My 2014 Beta wheel looks the same as the Rev3 but the Rev3 has a bit of a floating disk. The GG disk locates on a lip on the hub where the Beta disk does not use the locating lip but I guess it could have been included..

Will a Rev 3 rear wheel fit an Evo? On the same note, will a rev 3 brake pedal fit an evo. The late model evo has a short pedal which decreases leverage. Maybe I dould start another about the brake pedal.

Can you fit 2004 Gas Gas wheels to a 2016 Beta? (A friend wants to use them as spares.) After taking some basic measurements on the rear wheels, it looks possible but would require sprocket and brake disk spacers plus wheel spaces so it doesn't look very practical. Has anyone does this?

I have heard one like that and it was bad main bearings from swallowing dirt. You could see if there is up and down play in the flywheel.

The general term is T Nut or T Slot Nut. They are used on machine tool tables. The term T Nut also applies to other similar looking nuts.

re there good sources for parts in the US? Specifically looking for parts like the OEM countershaft circlip and spacer from Honda as seen here at Trail and Trials UK. for when I run the smaller counter shaft sprocket. As I remember OEM front sprocket had some kind of bolt on retainer but could use a clip. Spacer like the one on the link can be made from the OEM retainer but if you can buy them so much the better. Bikebandit still had the retainer and some other OEM parts from Honda. A friend has a Reflex with oring chain and runs a 10 tooth with pvc spacer to keep the chain from sawing into the cases. A couple of spacers like on the link would be better. Talon made a 9 tooth but I don't know where you would find one. I ran 9/ 44 for trials and it was OK. You will want rim locks even thought the bike has little power. Even with on rear rim lock, I once spun the tire enough to tear the tube.

I'm asking about the top hat style steel plates. The extended lip fits inside a fiber plate but I don't understand the advantage. See pictures in link below. Mine has two plates like that but there should be three. The insert image function is not working for me. Your link did not work for me either but I think I have that document. http://s103.photobucket.com/user/mcman56/media/IMG_04271_zpslntivgzm.jpg.html?filters[user]=24355982&filters[recent]=1&sort=1&o=1 http://s103.photobucket.com/user/mcman56/media/IMG_04301_zpsmq5nilp5.jpg.html?filters[user]=24355982&filters[recent]=1&sort=1&o=0

Can anyone explain the differences between the standard Beta clutch and the Factory clutch? What is the advantage of the factory steel clutch plates, the ones with the top hat shape? The 14 parts list shows a different drum for the standard 300 and all of the smaller Factory models? 125 to 250 standard models have a different part number. What is different about the drum? The factory clutch kit on the Beta USA web site comes with a different clutch case. Is it dimensionally different or just hard anodized? The 14 parts list shows nothing special for the Factory. The kit also comes with a slave cylinder. Is it physically different or just a different color? The 14 parts list suggest that the only difference is that it is black.

I'm not sure what the clubman line is but I had one of those and weigh about the same. It did everything OK but go up hill. It struggled on most any kind of a climb. You could use the clutch to lift the front wheel for logs and things but even mild climbs were full throttle with the motor spun all of teh way up

I see there are ti dog bones with grease fittings. How does the grease get to the bearings? Are the bolts drilled through for a grease path? Are they a larger bolt diameter than oem? Are the inner races cross drilled? Are the bearings the same size as oem? Or...how do they work?

American houses have 110 V and 220 V single phase. 220 is generally for dryers, stoves and AC. 220, 230 and 240 generally run on the same power. Our 110 is also called 115 and 120. Businesses generally have 3 phase. I have never tried to get a measurement but suspect that you are right in that energy efficiency is not one of the little heaters advantages. My garage is attached to the house. The back wall and most of the ceiling are covered by the house. The garage doors are insulated and I only run the heater when I'll be in there so it does not run 24/ 7. FWIW, the garage doors face west and temperatures over 100 are common in summer. The insulated doors keep it much cooler in summer.

I have one of these in a 3 car garage and it works quite well. It is small, cheap and powerful but the fan is a bit noisy. With an appliance power cord, you can make an adaptor to plug it into a 220 volt, 30 amp dryer outlet. It is not made to be hung from a ceiling but the top bracket is welded on and holds the weight. http://www.ebay.com/itm/Dr-Infrared-Heater-240-Volt-5600-Watt-Garage-Workshop-Portable-Space-Heater-/351536815571?hash=item51d93a1dd3:g:5sAAAOSwKIpWDotD

Same carb is used on a lot of Japanese 80/85 cc MX bikes so other dealers may have them also.
