BAD VIBRATIONS POLL!
Does your China DS have bad engine vibrations? If it does, tell us what make and model it is and whether it is a pushrod or OHC engine. If not, tell us anyway!

06 Lifan Gy2. Had vibes, but rebolt fixed it.
Edit- I have a pushrod engine. Edit again for Porterz. Engine rebolt was done last August at about 1000 miles. 4000 miles since. I don't do alot of off-road, but about 50 miles has been done since the rebolt. Allen

Well it's also important to know how much offroading they do and if they put new bolts in how long since they put the new bolts in have they used their bike and what is the result. It seems like the offroading irritates the mounts. Offroading with medium to high revs in particular.

Roketa DB-07A - OHC - NO annoying vibes. Could even be described as smooth.
Roketa DB-07B - Push Rod - with 49 tooth sprocket - cruising at 50-60mph very similar to OHC (No annoying vibes, could even be described as smooth), but between 35-45mph could be considered annoying vibration that is felt in the butt and feet. Weighted bar ends take away any from the handlebars.

2007 AL g20-5 . counterbalanced motor (lol), not bad vibes for about 500 or so kilos then they started. tightening back motor bolts helped briefly. vibes are back. did total engine re bolt with grade 8's and still vibes. could be worse I suppose. Its bearable but annoying. if i paid 4000 it'd be VERY FREAK IN ANNOYED. but I've just learned to accept them. maybe some fancy gel handlebar grips would help.
oh...i basically do no offloading unless you consider the occasional crappy country road. |
