It only has 1,500 miles on it, but won't power wheelie even in 1st gear. I heard that this has the Raptor motor, which I had one that I rejetted, removed the airbox with straight K&N filters, and a homemade glass pack straight through muffler. It ran like a raped ape, and would start without the choke in 1/2 of a second even after sitting for a couple of weeks. 3rd gear power wheelies could be had by hitting the throttle at pretty much any RPM. It readlined at 70 mph, and I know this Baggie is geared to do over 100. The PO said he was measured at 120 with another sportbike next to him, and this bikes speedo was pegged. I believe the spockets are stock, and them and the chain look brand new, kind of like they should with only 1,500 miles. I think it needs a smaller front or larger rear sprocket. I don't need to go that fast on an enduro, but even with this gearing it should wheelie in 1st and I was hoping even in 3rd.
My questions are these after spending a couple of hours searching this website:
1. Where can I buy or download a manual?
2. What is the difference in this motor and a raptor, 2004 series? I have seen different carbs on this website for Skorpions, and assumed all MZ's with the 660 Yamaha were the same, but maybe not. There is a wealth of info on the raptor forums, but I don't know what is the difference.
3. It has a D&D slip on, which is quite loud, and appears to be a straight thru glass pack, with no packing probably. What is the stock jetting these bikes come with? It pops badly on deceleration, like the pilot jets are too small. I am willing to bet they never rejetted after putting the D&D on, and it is too lean. It seems to have good power, but no snap to pull the front wheel. At 65 mph in 5th it will pull, but no wheelies in 1st. Backing off the throttle at WFO doesn't change things, so the main jet seems OK, but I still would put a larger one in to see how that works.
4. Is the rev limiter different than the Raptor? I don't remember ever hitting it on my Raptor, but this bike hits it just as it is accelerating hard. That is not keeping it from wheelieing though, as the front wheel should already be waving the flag way down the RPM range from the limiter. I could deal with a lower rev limit, but is the CDI or something putting a different advance curve to this bike as well as a lower rev limit?
I am in FLorida, so basically no elevation, if someone else has one to suggest their jetting. I won't be riding in any serious dirt, mostly street, so I was planning on doing the same mods to the air filtration I did to my Raptor. I have welding and fabrication tools and ability.
Thanks in advance for any info. I always liked this motor, and look forward to making this thing jump like it never has.
