sticky throttle on my '01 honda 400ex

Recommended Posts

I am having trouble with my throttle releasing too slowly. I recently installed a brand new carb and throttle cable. I have good throttle response but when i let off it slowly idles down. I have lubed my cable and checked for binds in the cable. when I take the cable loose from the throttle drum, both the cable and the throttle drum operate properly but when I put the two together it malfunctions. Any suggestions would be greatly appreciated. I am pulling my hair out here! lol

Is there a vent hole in the cap on the carb where the cable mounts?? It almost sounds to me like it's creating a vacuum in between the cap and barrel. makin the slide release slowly. I've see this happen on older snowmobile round slide carbs. Whe they ice up it slows throttle release dramatically.

      has anyone tried these cheap carbs from china? the original carburetor has been rebuilt by a shop right before i bought this quad and i think the float is shot the work done was way sub par... the price of the seal kit was as much as the whole carb... i have used the china 150cc engines with no problems... and have used the harbor freight 212cc engines on mini bikes.. so im hoping to hear so one has used them on this model with ease.... if no one replies i will update in a day or 2 i got the carb it looks very well made. has the carb sencer and warmer all ready installed..

      Hello there, i am wanting to know, what would be a good 4 wheeler with a manual transmission?  Either a real manual with a clutch, or a semi automatic transmission. Either 2 or 4WD will do.  What i do want is one that has a rack at each end and can pull a small trailer.   So what are your suggestions? I am open to most any brand though Linhai is the only one from China i would buy.    
         So far it looks like Arctic Cat is overwhelmingly what fits what i'm looking for, but like i said, i'm open to almost any make. If there is any rivalry over brands count me out, i like them all.   What i do want is one that will last through farm use, hauling feed sacks and so forth.

      The title is for attention. I’m prepping my cylinder head off of an unknown year 400ex to install on my quad. And I’m examining it and there’s literally a Jewish start( Star of David) protruding from the metal on the camshaft side of the head. It’s not imprinted or etched/ engraved. It’s coming out of the metal. DOES ANYONE HAVE INFORMATION ON WHY ITS THERE??? I’ve attached a picture

      So after my 400ex pep up (High comp piston, stage 2 hot cam, and some others), There was a malfunction with the rocker arm jam-nut; guess it wasn't torqued to spec. The rocker arm nut caused the lash to become too out of clearance and I bent a valve on a test rip high in the rpm range. There was no damage to the piston but only that valve, a couple dents in the head, and a completely destroyed valve guide. So I decided to take it upon myself (after watching kenoconnors race porting instructions and reading up on this subject) to port my cylinder head significantly. I had the head decked, cylinder honed and smoothed/polished the dome/exhaust port (intake wasn't polished but dimpled slightly to ensure fuel atomization). So after porting, decking the head, I had all valves and guides replaced/reamed, 5 angle valve job, and recut seats, then I installed xr400 gaskets (for higher compression), carb jets; 42 pilot, 175 or 6 main not sure, dynojet needle, k and n filter with no lid, enlarging of header ports and big gun eco slip on exhaust for a 450r, trx 250r coil (adds 1000+ rpm to limiter), 11:1 85mm piston, stg 2 hc with springs and retainers replaced, and polished rocker arms. I then replaced both sprockets one down in front and stock in rear, o ring chain, and 18in tires. There is a larger list of mods but these were the only ones affecting acceleration/performance. On the dyno, this quad put down 42rwhp and was estimated at 46 to the flywheel. Once again this was 42 to the wheel on the stock bore/carb size/header. All this was done at 16 yrs old. You may not be able to see it in the picture but peak whp was 42 on a mustang dyno.
