You need to use the correct plug.. And as far as i know the only one that you can use is the NGK IFR8H11.

But as far as why its choking and popping in the top RPM range it could be the main jet is a little rich, you could try going down a size or 2 on the main jet and see if it helps..

I`d loose that Dyno jet kit and find a HRC jet Kit made for honda !! air box lid on or off ?? Your probably hittin your rev limiter at max speed !! you can also do the Green wire mod ! That gives you a xrta 1000 rpms !!

In your opinion, With my 500cc motor, should i switch to an HRC kit or just go with an edelbrock carb?

as far as goin faster dude just get a big bore and make it a 490 or sumthin then you should have enough power to make you hap bc the little things arent gunna give you as much power or speed as it seems ur looking for, you could also experment with diff sprockets for more top end.

      I have a Yamaha YFM225 which sounds really noisy exhaust wise.  It had no baffle so I bought and installed that but it seemed to make no difference.  There are no leaks from the manifold or exhaust but the damm thing just sounds  so loud !

      '11 Grizz 700 here.  Since I've got some warm weather these next couple days I've decided to start the bike after about a year of just sitting.  Took out the plug and sprayed a good amount of fogging oil on top of the piston to help lubricate things.  After about a minute of letting it soak I stuck my air line tubing in to suck out the excess, but it seems like I didn't get nearly as much in return.  Repositioned the tube enough so that everything that was gonna come out pretty much did.  I'll probably shoot some compressed air down the plug hole before doing the start just to make sure it's all out, as well as cranking it for a second before putting the plug back in.   How long would it take for a bit of standing fogging oil to seep past the piston rings, and where would it go?  I guess into the engine oil?  The oil was fairly new the last time it was started but I'm sure it could stand to be changed after sitting for so long.  If much of this fogging oil got into the engine oil should I do the change before the startup?

      So I'm trying to figure out the year of one of my Timberwolf's. I have 4.
      2 are definitely 1993's, as I can read the serial number on those.
      1 has to be close to a 93, as the back rack and lug width (156) are the same as the 93's.
      The last one is killing me. Someone painted over the serial number.
      Listed are the differences
      Back rack is different. It goes through the plastics and will pivot on the rear attachment. Doesn't have the handles out the side, either.
      Doesn't have the loops coming out of front plastics.
      Foot rests are different.
      Lug pattern is 110.
      Everything I've read, says that the Timberwolf was produced from 92-98 and then changed name to Bear Tracker. Most parts are interchangeable through those years. Only change I found, was front brakes were upgraded to disk in 2001.

      Hi people ...I am thinking I will prob spend the next 12 months solid on here trying to get my 800 Hisun working right but that is life I guess....it all started when a very large lady sat on me in the bus when I was three...and things havent got any better since...my poor old 800 is pretty crook ...fuel wise and gearbox wise as well. I went on the net and saw a heck of a lot of posts from guys that are really enthusiastic about theirs and I thought  wow they cant be all bad...so maybe I can pickup some tips from your forum posts....I am currently removing millions of screws from the body to access everything and then I guess I will see if anyone has worked out the wiring and devised some tests....back to the screwdriver for now...

      My inside sources at Honda have told me that the new 450 will have an all new aluminum frame, EFI, improved geometry, and all new suspension. It should be out in 2010 unless they run into technical issues. The new 450R should put Honda back on top where they belong.

      IMPORTANT SAFETY RECALL NOTICE
      Dear TRX Owner:
      This notice is sent to you in accordance with the requirements of the Consumer Product Safety Act.
      What is the reason for this notice?
      In cooperation with the U.S. Consumer Product Safety Commission, American Honda Motor Co.,Inc. is conducting a voluntary safety recall of certain 2006 model year Honda TRX450R/ER ATV’s.
      Our records indicate that you own one of these vehicles.
      What is the problem?
      A safety defect may exist in the steering system of your TRX. The front suspension arm ball joints may have been contaminated during the production process, resulting in rapid wear of the ball joints and possible ball joint separation. If ball joint separation occurs while riding, the TRX could lose steering control and may crash.
      What should you do?
      Honda strongly recommends that you do not operate your TRX until it has been repaired. Parts will be available soon. We will send you another letter notifying you when you can go to your Honda ATV dealer for the free replacement of all four front suspension arms
      (Right/Left & Upper/Lower).
      If you must operate the vehicle prior to repair, perform the following inspection before each ride to ensure that the ball joints have not loosened:
      Visual and Physical Inspection of the upper and lower ball joints:
      Park the TRX on a flat, hard surface, such as a driveway or hard packed dirt surface. Turn the handlebars until the front wheels are aimed straight ahead. With the handlebars centered, grab the tire with both hands as shown. Push and pull the top of the tire while feeling for any looseness, listening for a clicking/knocking noise, and observing the upper and lower ball joint housings for up and down movement. Repeat this procedure on the opposite side. If you perceive any looseness, hear noise, or observe movement of the ball joint housing, the ball joint has excessive freeplay and must be replaced before the TRX is operated.
      If you do not feel qualified to inspect your ball joints, please do not operate your vehicle until it has been repaired.
      If you feel any excessive steering looseness or hear noise while riding, stop the vehicle and check the ball joints.
      If you have questions.
      If you have questions about this notice please call Honda Motorcycle Customer Support at (866) 784-1870. You may also visit our Web site at www.hondamotorcycle.com for more information.
      What to do if you feel this notice is in error.
      This notice was mailed to you according to the most current information we have available. If you no longer own this vehicle, or some information in this notice is incorrect, please fill out and return the included, postage-paid Information Change Card. This will help us update our records.
      We apologize for any inconvenience this may cause you. Thank you for your FourTrax purchase and your cooperation.
      Sincerely,
      American Honda Motor Co., Inc.
      Motorcycle Division
