Based on previous postings on this subject, if you buy the shaft for the motor that the clutch cover you have is from, it will protrude the right amount. There is a search facility for these forums where you can find previous postings on this subject.

thanks, I can find some but I need to know the lengths of these alternative shafts. Need one about 9mm longer.

Hi does anyone know of the correct jets and slide pin for the txt 70 cc Regards Neil

Richard Allen would probably have them.

Hi just seen this post 11 years later. Finally dragged my Whitehawk TY175 out of hiding under a tarp in the barn and its in the workshop to bring it back to reliable, presentable working condition. Engine is sweet as i rebuilt this years ago before it was laid up, but the gear change is like stirring custard. Did the photo of the bearing fitting ever get posted, as i would be interested to see it before i seek out a new cover plate

I can confirm that the 4rt rear wheel fits the pre 2001 315r with the 325r spacers and the newer brake caliper (the inside-swingarm one), but not with the old one. just checked it today.

Well that is pretty cool. I Googled "chapman bsa trials" and the first hit is here: Looks like the original builder was a member here (mick_99) and replied, "...20 production bikes and there were 3 prototype made:..."

One of the 1st mono shock trials bikes, built by a chap called Mike Chapman. Based on a DT175, hence why you thought it was a DT

What you have there is a Chapman BSA.

Is your frame cracked?

Looking on ebay, the DT style shafts are readily available.

I have a 2001. I was able to get air filters and a rear caliper but that is all I have needed. The 01 cylinder is different in that the lower water connection is through the cases rather than through a hose like later Rev3s. I suspect the later cylinder could be made to work but don't know for sure. I would worry most about getting plastics like a rear fender or air box parts. Are there sources for them?

Hi, the dials are not used but you can adjust the power, speed and response using a computer connected to the Kelly controller.

Hi anyone here using a Beta Rev 3 on a regular basis? They seem to be really good value currently.. what is the spares availability like? thanks in advance Kevin

What is the finger height measurement? If it is too low there will not be enough leverage to disengage the clutch. this is from the 2015 users manual, finger height is 17.5mm +1mm -0mm, other years may have slightly different measurement specs.

Anyone any idea why my clutch is pushing against my casing when I am pulling it in just out new plate in now clutch won't work

Hi is anyone selling a short gear lever for a beta rev 250 thanks mark

It looks just yours is the model before mine ie original ty frame modified. Mines a mk1 godden frame my grandad ordered it new from john in 1980ish and is a 320 as well. I've just started to sort it out as it's sat in my dad's garage for about 20 years. I have swapped forks and wheels to mono 1s but the others were seized solid

Hi, Does anyone know where I can obtain an electronic copy for a 2024? Thanks!

Was it put back correctly. It only goes together one way. The finger tower has a notch in it and the pressure plate has an aligning mark.

mine failed internally, didnt fancy the £150+ for a new one so replced with manual version. basically a bernard mower fuel tap (M10 X 1 thread) https://sjtrials.com/products/beta-evo-rev-80-fuel-tap?variant=36215746625704&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&srsltid=AfmBOopCHYgFHOdrIJIDj9G5nNaVCq1ZammULxk_gtt_tgsWnTlV80zZeFw

That U shaped bracket came with the footpegs

I agree with lineaway, I have seen and fixed more than one buddies brakes because of contaminated pads over the years and most often its an oil based product, including but not limited to WD40, that got on the pads. Comments are always something like, but its just a little over spray (of what ever the product was), and no matter how much cleaning, heating, or other attempts I have tried to get it working again in the end only proper cleaning of the disk, new pads, and a good heat cycle and water quench has been the fix. My exp and 2 cents for what its worth.

Although this information is for North America https://en.wikipedia.org/wiki/Vehicle_identification_number many European manufacturers use the 10th character in the same way. So M would be 1991 or 2021. Does that seem reasonable for the bike?

Can't figure out what year my TXT300 is. I've read many of these and it says the 10th digit which is M.... no idea what M is though. Any help is appreciated. I'd like to sell it. Thoughts on price? Runs great. VTRTG 3003 M120 6138
