here is a link to an online service manual for the honda helix cn250 engine. very useful info. some of the info is useless due to the fact its the scooter manual but the engine specs are good and useful. it helped me at first with my set up.

Is it possible to get a service manual cd and parts list for a Baja Motorsports DN 250

Thank you

Does anyone out there know where I can download a manual for the Kinroad Runmaster 250. It says it's a Raptor 250 but on the emisions sticker it says it's a Runmaster and the manual I got with the buggy is useless. It runs just fine and I can work on them but I need some pages to help me out. Hep me, Hep me!!!!

looks like the old blade xt that I had. there is a allen head set screw on the bottom of the gear box near the shift arm, loosen that and very gently slide the shift arm in and out until you feel a notch, when you feel the notch that is where the set screw needs to be. tighten up the set screw so that its in that notch.

also double check the shift linkage. heres a link to a video I did with mine and a link to a good engine manual

Looking at your videos, you have a setup like a Blade 250XT or Titan 250.

In one of the videos, it showed a loose chain. Did you adjust both the chains properly? Does this happen only in turns?

yes one chain will be looser than the other at times,

Yea the screw is in the notch k, and both chains are tight now, but still have the problem, i am just totaly outta ideas on what to do

where is the shift linkage link ?

there is not a manual for that. the way I did it was , put the shifter and tranny in neutral, remove the rod end from the shifter, put shifter in forward, put tranny in forward, turn rod ends until the center of the rod end line up perfectly with the shifter and tranny
