Checked for spark by grounding spark plug to the head and kicking over engine.

A little back ground on this bike then to my query. Picked up cheap 85’ XR100r for my kid. After a lot of fiddling it did run but very poorly. Cams and rockers turned out to be destroyed from lack of oiling. Took the top end apart and fixed that problem and replaced rings now oils properly and...

Thanks for that. OMG those carbs are difficult to get back in the bike. I definently see the appeal of the single carb conversion

Rebuilt these carbs from a 86' xv 1100 and have these springs left over Does anyone know where they are supposed to go? Sent from my SM-G900W8 using Tapatalk

Sorry about that. I've updated the ad to say Waterloo, Ontario. Asking $2400 steve

starts and runs well, 4 into 1 yosh exhaust, tons of new parts, needs nothing to safety, ownership in hand, located in Waterloo, Ontario, can help with delivery, side covers sitting on workbench when I took pics. More pictures available upon request. Asking $2400 steveandnic@rogers.com steve

I bought a 1979 cb 750 dohc some months past. It came with a period yoshimura full exhaust system 4 into one. It also had a stock, fairly old and dirty air filter. The thing runs but poorly and loves to hang when driven under load at 4000rpm. There are no air leaks at the rubber boots and idles...

put the lip up and reassembled. Nothing leaks, must be correct! When I looked closer, there is a tiny lip on the outer part of the ledge of the fork bottom where that washer goes. That lip (on the fork bottom) seems to sit under the slight arced edge of the non-lip side of washer- I just read...

thanks for all the help. Looked into the rec/rel unit and seems like a no brainer. I may rewire that gound, plug it all back together, retest the charging sysytem thoroughly before I buy the single unit. I have a tendancy to buy before I'm sure its needed, which at the end of the project =...

Before everyone jumps down my throat- I have researched this! I get lost in the technichal jargon of it all so please go easy on me. As you can see in the pics the green wire between my rectifier through the square connection, all the way along the wiring harness to where it splits near the...

A new query concerning my 78' cb 750k. Refer to pics below. Is the order of reassembly for the forks -fork bottom, washer, seal, circlip? That is how the fiche shows it but want to confirm. Also, when I took apart I'm not fully sure what direction the washer faced -because it has 2 distinct...

thanks rider52, I just realized one can buy them individualy. I figured I'd have to buy a full set. Crisis averted!

as the title says. I need one spoke and am too cheap to buy a full set. Anyone got one laying around? steve

thanks for the reply! Wow what a difference a second set of eyes on something can be. I've been looking at that for ever and didn't see it.

picked up this last week and upon my prelim check I find some oil/grease build up as seen in 2nd and 3rd pics. Initially thought head gasket gone but compression is 120 psi x 4 cylinders and same staining in the spark plug cavities. Any ideas of its origin...

there they are. Ive got to open my eye balls once in a while!

great advice! Thanks

noticed on my carbs that the air/fuel screw seems to be missing a rubber o ring. The fiche show it there, but might it be they were not used? It seems to be that most carbs of the era did have both a metal washer and rubber o ring under the spring. If anyone out there has thoughts on this please...

started on the carb 1 today and the main and pilot jets (think thats thier names) are plugged solid. No wonder it wouldn't run. Off to work next week. Will post some pics and progress next week. Good to know those ignition parts may be salvagable. All the ebay stuff looks as bad as mine.

hey guys, glad to be back on the site. Spent the last little while with my mid 90's sportbikes but now have a 440 ltd destined to be a rat/ cafe. I have a question about pic 1 that I have cleaned up to look like like pic 2. Essentially is it usable even with all its pitting? The bike turns over...
