    Last night , I was going to install the jack shaft kit I ordered to be sure every thing fit ok . HAHAHAHAHAHA after fitting the small top sprocket to the jackshaft I found my chain wanting to go 1/2 inch deep into the timing case.
    I took a good 2 hours trying to figure out a way around this , an the only one that made good solid sence was !!cut out the bottom bracket an move it to a more sutibale position!! So I moved it down 4 an 1/2 niches an back 3 an now the chain just clears the clutch case by 1/8 inch , going to make a small guard for that area but heres pics sorry no befores I was that p.oed at my self , but all happy now .

    Is that a custom frame, or store-bought??
