FJD Posted October 26, 2022 Share Posted October 26, 2022 Cant contribute, but is that already with camchain tensioner in ? 1 Quote Link to comment
Devilman Posted October 26, 2022 Share Posted October 26, 2022 (edited) That's no mongrel, that's a monster! Really nice combination of parts, should be a fantastic engine Combine it with a 1052 clutch and it's pretty much my ideal engine What clutch are you planning to go with? "Top-hat" style from the earlier 1052, or diaphragm clutch from the 1127? Regarding the chain, I'll echo what @FJDmentioned above, have you already got the tensioner installed in the back of the barrels? If so you'll quite possibly be fighting against it Edited October 26, 2022 by Devilman Quote Link to comment

Ted M Posted October 30, 2022 Share Posted October 30, 2022 It’s an interesting one almost like the cam chain isn’t sitting on the crank sprocket properly. I would speak to @fatblokeonbanditas he has built a couple of dot head 1200s. What is the purpose of polishing the oil pump? Quote Link to comment
Swiss Toni Posted October 30, 2022 Share Posted October 30, 2022 @Ted MYou might have something there! I’ve had the camchain appear too short, only to find the chain was located on the front and rear of the crank sprocket, with a lump of slack chain hanging below it. Put my hand through the chain, and turned the engine over by hand. Job jobbed! 1 Quote Link to comment
