I got the handlebars tore down and the new ones mocked up. I'm going to cut the bars down a bit. They're a bit too wide.
Also - I did a few test runs and I only got up to 30. Acceleration was good initially and got to 30 in good time. However, the RPMs were too low to push past 30.
When I first got it together it fired up great. Ran well. Then I installed the CDI...It started and ran. I did a quick run with it (no speedo at that time) and definitely heard it go above the stock limit previous. I shut it down, put the battery on the charger and began to do some more handlebar work. After I hand the bars sorted out/mocked up, I wanted to test the Rcuk speedo I frankenstien'ed together.
After starting, it started to run not great. It wouldn't rev up when I turned the throttle. Then it wouldn't start up at all...
I double checked the CDI wiring and disconnected the CDI and tried to run stock again...No dice.
I'm thinking i'ts the fuel pump. My tank is not rusty inside at all and I just replaced the fuel filter, so I don't think it's a debris issue.
Any hot tips as to how to easily test the pump? Disconnect the line from the carb and give'er a go? Voltage test?

Ok so update 2 -
It tested the pump, and it appears to be working just fine...
I let it sit overnight and soldered the CDI power connection yesterday afternoon (I think junky push connector wasn't making positive contact). After soldering it still wouldn't start.
However, after letting it sit until early evening, it restarted after much time on the starter and playing with the air mix...
Now the met GETs running, but bogs under acceleration (when I had it running before, it would bog under full throttle too). I believe that I have 82MJ in, so I'll plug in the 80 if she feels like starting up consistently.

Did you test before the CDI install? What carb? I run a PC10 (20mm?) 32SJ 82MJ. Middle clip.
Does everything spin freely, Clutch, rear wheel?

I did some testing before the CDI install. I got that sorted out now.
I am running a pc20 clone. I have 32 82 right now. I haven't touched the needle.
I'll have to start playing around with the jets

Are your sliders in upside down?

32 SJ is too small

I think sliders are in correct - flat top facing up. Acute angle towards center.
38sj* sorry...I'll check the pin position and all tonight

Re-reading the thread. Looks like valves hitting the head were a combination of the case milling and the DCR cam which has a longer duration than stock.
Obviously you should be GETting more than 30mph. Keep us up to date.

I would 100% agree with your analysis there...thanks to you it wasn't too expensive.
Yes - I need to tune fiddle...STAY TUNED!

Welp I'm pretty stumped. I think I have electrical issues or something.
Every time I start it up it runs for a little bit then it runs fine. Then when I start to try to ride it and immediately starts running like shit... backfiring and sputtering.
Also when it is running it does not like to go much above 8000 RPMs. I installed the CDI and double-checked everything and I'm not getting past that limit. In fact it actually bogs down near the top of the Rev range and wants to kill whole engine.
I am kind of at a loss as of what to do. At this point I'm close to scrapping it and seeing who wants to buy the parts. This project is continually turning into problems that are beyond what I know how to solve and becoming less fun with each new issue that I have no idea how to resolve.

I took the cdi off to tune properly.
The GET is still running very inconsistently. Throttle response is a little laggy but not bad. The issue is when I rev up it is fine once but after a few times but bogs down and dies.
Also - every time I take it off the stand it dies and doesn't want to start for a minute.
I'm still stumped and frustrated

I'm still stumped and frustrated Maybe your float height is too high and its running the bowl dry? The starting issue sounds like too rich, my 150 is pretty rich and especially with the slide carb, gotta give it some gas to start. Theyre picky and hard to tune |

Start working backwards toward stock. I.e. put the stock intake and carb back on. I had a small hairline crack in that JC cast intake that I couldn’t even see. Drove me nuts for a while.

Okay so I found one major issue that is causing some of/ most of my headache... the wiring from the alternator/stator was a bit melted from the exhaust. The green wire and white with green trace were exposed and shorting out on the frame.
I isolated them and now I start and idle fine. I am now starting to actually tune the carb this weekend since I fixed that issue.
I think i have my pilot jet right as 0-25% runs great. 25-75% needs help so im going to adjust the needle next. Power jet seems ok but I want to sort midrange throttle response first.
