well here we go, what i thought was going to be just a little paint and elbow grease turned out to be a complete tear down, looks like the powder coating is gonna cost more than i paid for the bike ? the Kosman spoke nipples have surface rust so they are gonna be reworked, front wheel is 18" and rear is 18X4'5 found some 290 mm rear shocks to keep the stance low, No Chrome whatsoever on this build all Ceramic Chromex on the RC headers and engine is now Black with Superchrome powder coat side-cases and valve cover, taking the frame in tomorrow for sandblast and powder coat, lots missing of coarse the factory gauges are missing with what appears to have original Tach still (oh-boy) and the wire harness just got tossed in the trash, what was left of it lol, Motor ran good on startup when purchase and have cracked open the valve cover to see nice clean cam and oil with no visible wear,still looking for #s to identify what the heck i have here ? anyway been looking around this forum and see a lot of beautiful builds any advise or thoughts chime in, should have some powder coat and motor pictures next week for update, yep i have a full time job too so just trying to pick at it every couple days .79 Dragbike resto

Re: 79 Dragbike resto
What displacement do you have in the motor? You may have to buy a separate head gasket to fit the bore. Athena kits are nice quality, but mostly come with standard bore head gasket.
I am a little confused (as usual): Did you have the motor apart already and paint it black? It sure looks different than the one in the bike

Re: 79 Dragbike resto
sorry for the confusion, i did not pull the barrels or the head off...so i don't know what bore it has, and can't find any #s on the cams to identify, the previous owner is a acquaintance and he purchased it 12 years ago, he supposed to get me more info from the builder still waiting ,,,Headport is opened up real nice on the intake and exhaust, thought about breaking the motor down but it sounded to good, but i really want to drop the pan and check the oil pickup screen and need Valve cover-Clutch-Alt-side covers- copper exhaust O rings- so i figured i could just hang the Head gasket and barrel base gasket on the wall, thanks for the Info EMS..btw just did a degrease to the motor and cleanup with paintEMS wrote:What displacement do you have in the motor?

Re: 79 Dragbike resto
You can use calipers to determine bore size (with the head off). I doubt very much that the stroke is different from stock. Would mean a custom crank.

Re: 79 Dragbike resto
thinking the same thing , really doubt it's a stroker, gonna ask around and find a shop that may have this tool to check bore, the liquid volume tool like NASCAR would use is in Cubic inches , not sure how close it could be for CC's on a small bore, no reason to pull the head off, maybe take it down the 1/4 mile and see if it still puts up the numbers it did years ago is all i care lol

Re: 79 Dragbike resto
Judging from that, I'd say your cornering clearance is about zero.

Re: 79 Dragbike resto
I don't think Bob is a member. Doesn't matter, though. He is a great guy to deal with and a long-time CBXer.
I had bronze bushings installed in a stock 79 swingarm and they were a huge improvement over the (deteriorated) plastic inserts.
You can take it up a notch and go for the needle bearing kit that Bob probably sells too.
