I'm getting ready to rebuild my 45 and am contempating stroking it. I'd like to get some feedback from the guys that have done this. Was it worth it? How noticeable was the performance improvement? Are there more problems or issues as the stroke increases (clearances, necessary mods)? Any feedback would be appreciated. There are a lot of posts mentioning stroking the 45, but not many that actually give info on the performance increases. Thanks.
Best thing you can do to a 45, I have just done mine, 4&7/16 stroke .070 pistons, all done as per booklet you can get, KHK cams advance 1 tooth on the inlet, heaps of low down pull, i ride at 55mph, snap the gas on, I see the front forks rise up as I axcell off down the road, have only done about 300mile on the motor , when it is run in abit more i will see how she really goes, after ridin the stroked motor my stock 45 is boring. but cool. Lota work bit worth it. cheers Rod
