mac Posted June 29, 2009 Report Share Posted June 29, 2009 Ive got one on a 08 , really like it , after having a 200gasgas which I thought was the best bike ever. This is its equal with more power. Quote Link to comment Share on other sites More sharing options...

benz19 Posted July 12, 2009 Author Report Share Posted July 12, 2009 Are both you guys using Kiehin carbs or standard? Im on my way,have now fitted a 125 engine into my 7 month old 08 chassis,going to run as 125 for a couple of trials to get abench mark then change to 225! Done my first trial today as a 125,what a fun bike to ride,does not tire you and does not drag you thru the section if you get it wrong!! Really keen for 225 now!!!

benz19 Posted August 1, 2009 Author Report Share Posted August 1, 2009 Rode my new 225 for the first time today...........................WOW! Really great fun bike to ride with loads of power and really soft off the bottom,bike feels light and much more agile and stable due to less engine inertia! Three other guys rode it,an expert champion,clubman tip rider and a younger guy who has a 125,everyone loved it and did not want to get off it. Spec i ended up running..................... Gearing 9/42 Dellorto carb with 125 jetting short front pipe two 125 flywheel weights Benz Quote Link to comment Share on other sites More sharing options...

Gearing 9/42 Dellorto carb with 125 jetting short front pipe two 125 flywheel weights Benz Interested in the two fly wheel weights; I'm running one at the mo' and think it could be a bit softer at the bottom again, how do you attach the second weight? Mine was a shrink fit onto the flywheel boss. Quote Link to comment Share on other sites More sharing options...
benz19 Posted August 1, 2009 Author Report Share Posted August 1, 2009 (edited) Gasgas machined and then welded two together for me. Then just shrink fit as you do with one,but i added a couple of spot welds to hold them onto flywheel to be safe.

Benz So it's a double thickness then? Do you need to space out the flywheel cover as well? Ta for the info! Quote Link to comment Share on other sites More sharing options...
benz19 Posted August 2, 2009 Author Report Share Posted August 2, 2009 Yes i use a gasgas flywheel cover spacer. Benz Quote Link to comment Share on other sites More sharing options...
mikee Posted August 2, 2009 Report Share Posted August 2, 2009 How are you finding the gearing 9 / 42 ??? I've only rode one 225 and this had the same gearing and i found it to way to fast for me. (but then i aint to good ). i'm looking to take my 200 out to a 225 soon, so i'll follow this tread with intrest. cheers mike Quote Link to comment Share on other sites More sharing options...
benz19 Posted August 3, 2009 Author Report Share Posted August 3, 2009 The gearing seemed good,was going to try a 10 after the trial but did not get time. I think the 9 suits,although the capacity has increased the stroke is still short as its the 125 crank.so she revs up quick,but controllable. The 125s run 9/48 so 9/42 is quite a increase in the gearing,plus this is what Factory Kevs uses,and another good expert rider i have spoken to said that when he went from 10 to a 9 it transformed the bike?? Got a good road trial on it this weekend so will have more info then. Plus im planning to try a Keihin carb next???? Benz Quote Link to comment Share on other sites More sharing options...
john.b Posted August 3, 2009 Report Share Posted August 3, 2009 Can you buy a new bike already modified or do you buy the 125 and then add the kit yourself? Quote Link to comment Share on other sites More sharing options...
benz19 Posted August 4, 2009 Author Report Share Posted August 4, 2009 Gasgas will build one for you if you buy a new bike,they start with a 125. Benz Quote Link to comment Share on other sites More sharing options...
jandyb Posted August 4, 2009 Report Share Posted August 4, 2009 If buying a new bike is there a point buying a rebuildt 225 rather than a stock 250? I guess the characteristics are totally different, but wich is better? -Jan Quote Link to comment Share on other sites More sharing options...
