So Close!...
-
Got a new crank ordered from PJME. Just waiting on it now. Need to get a bolt lug welding on to the flywheel side of the crank casing and I’ll be good to start building this thing…

I don’t have any experience of elecy start lumps. So I want to remove the flywheel and starter clutch-ring stuff and see how it sounds without all that gumpf.
There’s no (up/down) movement in the crankshaft apart from a bit of side to side, which I can’t say I remember ever seeing before. I don’t know if that’s normal?… -

Crankshaft? Or Connecting rod?
There should be some side float, no up/down movement.
The starter bendix will make some noise, but otherwise it should be silent.

I meant crank movement, only the tiniest bit
…Bendix? Sounds like something Uri Geller would do in the bedroom!
…While I’ve gotten some free time I’m gonna tackle the water pump seal on the dtr. I’ve been meaning to for a while now. The oil has an opaque milky look to it where it’s been emulsified with the coolant.
I need the new seal I have for the tizzer now though. Luckily I’ve got a spare clutch casing with good pump seal, ect… -

Even for the gearbox breather tube. There are loads of other guides and clips missing from my bike. I would really like to know where they all go so as I can try and replace them…
Anyone got ideas of how to find them out , short of doing a walk around a totally standard survivor bike?… -

Are they not itemised on the exploading diagrams?

Damn this has gotten a lot worse than before!…

Buttery gearchanges now, especially since oiling the clutch cable as well. Feels like an even newer, different bike! Feels like the rolling resistance is better as well, or I’m imagining it! Ever way it’s a plus

When I fitted the new clutch casing I omitted the oil pump. I never realised that the bottom screw bolt isn’t blind like the top one. It goes straight through to the gearbox for some reason. Ended up with a boot and a back tyre/disc full of oil. Won’t make that mistake again … -

Engine's okay though? Just leaking gearbox oil through the bolt hole! Doh!

Hi guys
Off the top of your head what psi are you getting on compression test?
Thank you! -

I gather it’s different if you have the power valve pinned open or not. I don’t think that there is a definitive standard to gauge a ‘normal’ from…

I just got 140PSI on my Cagiva raptor. Did it on Sunday purely out of interest.
But this engine is worn and I'm just in the middle of a rebuild as we speak.
That said, 140PSI is good for a two smoke.

Perfect thank you everyone

Yep, the 2T pump lower 4mm screw/bolt hole goes all the way through to the nylon cog on the inside…
Plugged it with a screw/bolt…Oil & brakes? Who would of guessed?

Only thing is that the right side indicators have stopped working along with the indicator dash light. Also got to wait for PJME to get the crank in stock. Always something on a 35 year old basket case, eh?
Also got the new headstock bearing half way on and it won’t budge!…

First one I’ve done on dtr though I did one on a kx and the tolerances was so tight it didn’t work I had to get a tube that fit over the stem and onto the inner race and long enough to clear the top and few taps with hammer got it seated, wouldn’t damage the bearing as all force was on the inner race -

Lots of little spring-loaded leccy contacty things inside them, it's a harsh environment for a switch. Good post-jet wash routine to get into

gonna investigate it some more today…I had it in the freezer for a few days! It was so cold wd40 was freezing on it into slush, couldn’t heat the bearing though. It has the bottom rubber seal fitted into it. Never seen one like it before…
Gonna have to find a steel pipe

It’s been bugging me forever since getting the bike! The headlight runs off of a/c directly from the stator coil, but the brake light is run off of the battery, it shouldn’t affect it! The only thing I can think of is that they share an earth?! I’ve just rigged up an earth to the frame straight from the battery. I’m gonna see if that helps any. The neutral light looks stronger anyways, as is the PV on the key
…Fixed the indicators (& intermittent speedo bulb). Six new bullet connectors behind the headlight!! (& 1 bulb) The last couple years have been hard on the loom! Everything looks brighter on the battery now
…Almost forgot: This may sound stupid, but: 2T oil from the exhaust ‘filming over’ the battery top, could it diminish the output amp/voltage? Mine was coated and the power valve & neutral light had gotten ‘sluggish’. It’s better since cleaning, but I’m not sure if it was this or a poor earth to the battery? I guess I’ll try not connecting the earth, later after night testing…
I wish I knew a motor cycle electrician/Wizard
