[QUOTE="RossKean, post: 1182575, member: 19880"] James With 124000 miles on my bike, I probably should check compression and leakdown. (Like you, I don't think I really want to know the answer if its bad.) As it was suggested, a Ringfree enema might be a good idea. Won't hurt anything and might fix things up for you. Similarly, running some Seafoam for a few tanks might help if valves are carboned up. While I am not a big proponent of regular additive use, I would probably at least try these before I condemned the motor. Regarding your upcoming trip - do it! I seriously doubt that its going to go from low compression to dead in a few thousand miles. AFAIK, any of the non-AE engines from '06 to '12 should work. (Somebody will correct me if I am wrong!) Don't think the air filter is going to make any difference in the compression result. Out of curiosity, have you had the throttle bodies out to be cleaned/examined - wondering how they look after many miles with the Uni filter compared to the OEM. I have seen some ugly TB with the regular filter and wonder whether the Uni is better or worse. (If worse, it might be a contributing factor to the apparent engine wear, although its too late to change anything now.) I wish you lots of luck on this and would like to know what the investigation reveals. Totally off topic: While I was riding and camping in Newfoundland this past August, I met a gentleman who apparently knows you quite well. (Unless there are other FJR owners in Japan with 200,000+ miles on their bike) Forgive me if I mis-remember the name but does Cyril ring a bell? We had a pretty good chat around a campfire at one of the provincial parks. [/QUOTE]
