  1. This thread is brilliant, but how about some pictures of these bikes and their mods ?
  2. stevieb, I may be able to help you. Drop me a PM. Regards Archie
  3. stevieb, I think you'll find it's the same casting. The second one does look a bit rough mind (!), but nothing that a bit of high build primer and a silver top coat won't sort. All the Scorpa four stroke 125/175/200 derivaties are based upon a stock TTR125 engine, and so casings etc., are usually pretty easy to find. The gaskets are pretty expensive, but can usually be re-used if removed carefully. There is a load of info on this forum on mods to these bikes as well which is worth checking out (if you havn't allready) which is where I got allot of useful info when I got my bike.

    Interesting, thanks.

    Scorpa Decals

    I ordered a set from Express Signs before Christmas which arrived incomplete. Despite numerous (polite) reminders I still await the outstanding decals

    andyrothers, you don't often see the mod to the clutch actuator mentioned much, but in my opinion it transforms the rideability of the bike and is one of the best mods you can make and if you can do it yourself, it's a no cost mod
  8. Hi ausy300pro Some food for thought: http://www.bjracing.com/sy125.html http://www.powroll.com/P_YAMAHA_TTR125.htm
  9. Nice job on the bash plate RodT. It looks so good I thought it was some new (expensive) after market custom part! Cheers for the tip on the Plastikote btw. BBQ paint lol, that makes sense, I'll give it a go
  10. RodT, Nice bash plate, did you make it yourself, and what did you use to paint your exhaust? Has it stayed on!? ausie300pro, have you tried out your lightened flywheel yet? What do you think?
  11. ausy300pro Glad to hear youv'e found a flywheel. I put my lightened flywheel back on again this afternoon as I was interested to see just how much effect having the carburation sorted has had on things. I will run it up a few sections tomorrow, but I have had a quick spin on it, and I was very pleasantly suprised to find that I couldn't get it to hesitate at all. I had it in 3rd going uphill only a really light throttle, and then whacked the trottle fully open - NO hesitaion! I had also fogotten just how quickly the engine accelerates with the lightened flywheel fitted. SOOOO much more responsive Can't wait to give it a propper go tommorow. Just out of interest, before I re-fitted my lightened flywhell, I took this pic of my original (standard) flywheel next to my lightened flywheel (donor bike TTR125).
  12. Whilst we are waiting for ausy300pro to find a flywheel, here's a pic to keep the thread alive. This is my 2007 TYS175, it's a full racing spec 163cc bike with the following mods: Exhaust box - all baffles removed Carb - Re-jet and set-up Cylinder head - ports polished, valve seats blended in and step removed from inlet manifold to inlet port Clutch - Actuating rod profile softened Throttle - Slow/super fast throttle Chain tensioner - Birkett H/D Gearing - 11/57 (have tried 10/57 & 10/54) Flywheel - Currently standard although have tried lightened flywheel Happy Christmas one and all Edit: Sorry, don't know how to make the link live, you'll have to copy and paste!
  13. OK ausy300pro, I took my lightened flywheel to the Post Office this afternoon to get it weighed. Result 1.53kg I know Nigel Birkett says the standard flywheel weighs 2.1kg, but I seem to remember mine (it came off a TTR125, paid £20 off fleebay) was 1.9kg. Anyway, all I am saying is don't go less than 1.53kg! I found that the hesitaion was more pronounced with the lightened flywheel (obvious really), but when I lightened mine, I hadn't got the carburation sorted to the extent that I have now. The reason I didn't want to sell mine was, now that my carburation is sorted I quite fancy having another go with it. The throttle response and acceleration off the bottom was quite something with the lightened flywheel. You are not talking about a small difference. I was very surprised at just how much difference it made. How you get on depends on your riding style I guess. I would be interested to know how you get on

    SY250R Tailpipe.

    ausy300pro, I don't want to part with my ligtened flywheel (sorry I should have made my post clearer!). I was just offering to weigh it for you, as if you are about to lighten yours then at least you would have a point of reference. I'll take it to work and put it on our postal scales which are reasonably accurate.

    SY250R Tailpipe.

    Sorry to hi-jack the thread, but excellent news ausie300pro " got forks sorted". I found mine were VERY sensitive to having the correct amount of oil also. Before you dive in with the flywheel, let me see if I can weigh my lightened flywheel first. Are you interested? I mentioned in an earlier post that I had bought a standard flywheel off fleebay and lightened that. Having riden the bike with the lightened flywheel, I went back to the standard flywheel. Throttle response MUCH quicker with the lightened flywheel, but I kept stalling the f*****g thing. Now, having got used to the standard flywheel again, I would say a half way house "may" be the optimum. One thing also to bear in mind. Have you dialed out that hesitation when opening it up from a light throttle load? I found it was more pronounced (obvious really) with the lightened flywheel. Much less so with the standard flywheel. What gearbox sprocket do you use. I found 10t too short for me and I use 11t. 11t plus light flywheel was may be pushing things a bit? Perhaps a subject for another thread, but interested to know what you think EDIT - Sorry for O/T guys, need new thread ausie300pro
