The 4-Stroke Blasphemy Forum / inboard starter clutch repair
Last post by m in sc - April 22, 2024, 11:45:10 AMWasn't aware the starter clutch was dying when i got this going... but it had gotten bad enough i needed to address it. That inboard design sucks, bad. had to drop oil pan, pull clutch cover & clutch, LH chain cover, drive out intermediate shaft, and pull oil pump.
LUCKILY i didn't have to drop the exhaust. mind you, i didn't rebuild his motor so had no idea what i was going to find in there. this was the oil pan, not a whole lot of debris thankfully.
this is where the starter clutch is.
you have to hold all that up and in line to get the shaft back in. you also have to slip the clutch housing w rollers onto the hub with it up there, has to go in and come out disassembled, after you pull the oil pump out.
the culprit: the old springs were about 10mm under correct length due to wear/age. thats it.
he parts were dirt cheap, same kit used on multiple makes and brands. Now, its all good and starts like new. reading about this repair, apparently its common for people to lay the bike over on its side and do this. I didn't see the need. the total repair took about 3 hours start to finish, and about 40 mins of that was cleaning up stuff like the oil pan, inside clutch housing, and unloading about 3 cans of brake cleaner int he open motor to remove build up. also a good time to clean off the sightglass from the inside. (dull pic and a handy wipe).

Turning Wrenches / Re: VM28 Float Needle
Last post by AAAltered - April 22, 2024, 11:43:23 AMSo here is the side view.
The needle sits well and closes well, I can tell by blowing gently into the gas line port.
If I tap the carb body, the needle does fall down a few mm. Is this normal?

Turning Wrenches / Re: VM28 Float Needle
Last post by 1976RD400C - April 22, 2024, 11:08:35 AMLooks like it is installed right. When I installed the vitron's in my carbs I noticed that the tab that pushes on it needed to be adjusted because the new needles stuck out of brass valve farther and caused the fuel level in the bowls to be too low (maybe I have the wrong needles?). Do you have a side view of the carb with the needles in showing that flat brass piece the floats push on and does it look level?

Turning Wrenches / VM28 Float Needle
Last post by AAAltered - April 22, 2024, 10:17:33 AMI am having fueling issues. Bike will not start. Petcock flow tested fine. A tad of fuel into the plug holes and it fires right up, but doesn't keep running.
I have suspected float issues for some time, I replaced the float valve with Viton last season.
Question I have, is this the corr3ct installation and orientation for this type of valve? My old ones didn't have any little clip on them. Can I run without these clips?

No secret recipe. That first start video was in the garage and it was all closed up. I did repack those Spec 2 silencers years ago. When I did that years ago I thought it got too quiet. My thrasher bike with Toomeys I have never repacked the silencers. It's loud and I love it. The 500 sings a good tune also. I'm sure your bike will sound great with those (Toomey?) pipes although the silencers look non-Toomey. Good luck.
