| Post subject: | fl250 with cr250 head |
I bought an rebuilt fl250 Engine with a (didn't realize) cr250 barrel and precision water cooled head. I want to install it with a stock CDI (Capacitor Discharge Ignition) ignition, carb, and exhaust. I have a bunch of children, grandchildren who ride my five bikes. Use ranges from an 8 year old who putt putts around, to adults who go flat out. We go to the Oregon dunes. The Engine had a racing past judging from the racing stator in it. My emphasis is on reliability, rather than performance. My question is will this Engine install with the stock components, will it be more prone to failure because of higher output? If I put a stock jug back on the lower end will it fit? Thanks for your input |

How is the jug ported? Any obvious alterations? Is there a reed cage added? Extra holes? Or just a stock CR250 jug? What size carb? Jetting? The cr250 one flows more, but to really see performance increases its just part of the puzzle. Without more air/fuel coming in and a free flowing exhaust, you will limit the Engine, which seems to be what you want, so i would say with adding everything you are listing, you would be ok, assuming everything else is stock and the carb is properly jetted. Got any pictures of your project? |
