Hiya Peeps!
I have some questions & comments...
First post here. Joined this forum to respond to this post.
I have a Zongshen 190 in a 2018 Pitster Pro LXR 190F That I just purchased a couple weeks ago. From what I hear mine is the third bike that has been sold in country (USA).
I only have .3 hour on this machine so I do not have much seat time.
This is my first open cradle pit bike. No experience with this type of motor/machine, but I do have 40 years of motocross racing under my belt. I purchased this bike to race the pit bike races that are normally held at the bigger AMA races (nationals).
I went this route because I could not build up a KLX110 type machine and get the performance for the money I spent on the Pitster. I really do not think a 110 motor BBK out to 190 ish will not be reliable. Time will tell, eh?
I cannot find a wiring diagram. Need to get rid of some lighting wiring, add a kill switch and a starter button. Love to get rid of the key switch.
Cannot find a parts fische on line. Too new? Pitster too lazy?
Carb: Comes with a Jing KE 28 carb. 130M 42 P. I will prob end up replacing this carb with something that I can get parts for readily.
It came with a pod type air filter. ll squashed up against the frame rails. I have to correct that!! Don't know i fit will take another intake, filter or carb. Might take all of the above. Might even have to fabricate a box if I can find the correct sized box to carb rubber boot.
I m having some issues with the motor at 5-7K RPM. It seems like it is electrical. Almost like I am hitting the rev limiter. At this time I have to assume that it is electrical vs carburation.
Other than the above issue, the motor has fantastic low end & midrange. Clutch is nice & the gearbox gives a positive engagement.
What should my valves be set at and do I adjust hot or cold? They came REAL tight out of the box. I set them to 4 intake and 6tho. exhaust, cold. I am also seeing out there 3 and 5. Personally I do not think 1 tho. is a big deal. Although I have been wrong before.
All & all I think after I track down this top end gremlin this is going to be a pretty nice motor/machine.
