kfx450r

Weather starting to get colder..I now hear a single pop when I rev the bike up in idle. And excessive popping on deceleration. Can anyone suggest something for me? I have a 175 main, sparks needle, 2 and a half turns on a/f screw with a 42 pilot

What i meant by 4k and less than a mx quad is going all out. With 4000$ my bike will be pretty much as drag of a bike as you can possibly make it with as many parts as you can get. The only thing that wont be high dollar is the engine, becuz of course you can get more than 5k just in an engine. But comparing to amx, thats 4k and ive got a top of the line drag bike, to get a top of the line mx bike your going to spend ALOT more than 4k. But to each their own.

If you look at the four stroke war videos on youtube, the majority of the bikes you see with no plastics what so ever are TRXs, and thats what im going for. Pretty much a frame, tires, engine, handlebars. And they fly

So far ive added, as you can see, blaster shocks which are slightly lighter and lower the quad significantly. Removed front brakes, parking brake and all cables/levers attached to it, front light, front fenders, a few tabs here and there, nerf bars, heel gaurds, Have some lightweight drag bars on the way. Soon to come is a +6 swingarm (cant keep front down as it is without hardly any engine work!), ported head, bored carb, bored cylinder, possibly higher compression but still pump gas, and in the far future drag arms, axle, stem, lightened frame, spindle mounts etc. All in all for everything i want..is around 4000$..Which would be all out for my bike, which is alot cheaper than mx.

What did you do with your tank?

If you look closely, it's more like "What did you do with your tank, head, and cylinder?"

Actually, I thought my crank bearings were going out cuz i had shavings in my filter, but I hadnt changed my filter in a while evn after a cam install and nothing looked wrong after I tore it down so Im waiting for gaskets to get it back together. And the rears are Pro Wedge II's, but I just got some 4snows on rims for free last night so Imma try those out.

Well, Ive decided to go the Drag route. Heres some stock pics and what it loooks like now.

New Tires pipe, lid off.

Latest drag frenzy

Gaping hole of an engine

What kinda pricing would I be looking at for a drag port on a 450r, and a carb bored to 42mm if you do that also...And possibly stock cylinder bored to a 470 and replated on a 07 ER

where've you been?

Where? Workin on my bike for the last few weeks and school and work Im usually always on the 450r.org site getting answers to all my engine problems. Going pick up the shims i need tomorrow and see if it all goes together good.

thanks for the responses, yeah i checked them right and they were in spec the first time i checked them and i just checked them again today though and 2 are off by .001 away from the .001 tolerence, which im saying is .002 tighter than spec so Im going to reshim, my cam sprocket bolts were loose and 1 was hanging half way out even tho i loctited them.

Well, in process of installing cam, all the clearances were in check timing was on on a new hotcam stage 2 and I started it up and the engine is much louder and i hear a littl rattling noise now and it dies after idling for like 3 minutes. Could this be a bent valve? I really dont wanna take off the head right now.

Imma drill em, so many people have told me its ok and have done it with NO problems on hard riding, + the rims are douglas .190s, which some of you know are some of the strongest rims. Plus there going on paddle tires, which means no jumping there strictly drag tires so theres hardly any chance they will break.

I love doing em when ever I get the chance but my local riding spot is all rough..No place to practice em and I dont wanna screw up my tires on the street. I went off the back doing a wheelie twice but it was on sand.

My friend is obsessed with wheelies..I love em too but my local riding spot isnt exactly the best place to practice them.

dude its your jets. if the clutch was slipping it wouldn't be pulling hard or bogging... you will know when your clutch begins to go...

I know, ive already said that i know its the jets..

And im rejetting it tomorrow.

I use the same oil in both sides. GN4 from the Honda shop. I change my oil about every 3 rides. I replace the filter every other oil change. I change the tranny oil at the same time. As for the tranny side, Honda recommends GN4 or HP4 without moly 10w-40 is correct. And I heard the synthetic will make the tranny slip.

Well..Like i said..I use 80/85 Honda performance tranny oil...the synthetic would be for the engine side..I never use the same oil in both sides so it wouldnt be synthetic in the tranny side.

It will do it in every gear.

iM prettttty damn sure its the jetting by now. I believe when i first noticed it when i was riding i was in 3rd..so yeah pretty much every gear.

FORTUNATLY my exhaust, jet kit, cover, filter kit all get here tomorrow! Woo cant wait to get it all in

Hey, bot, how often do you change your oil, what oil do you use and how often do u change your oil filter ...and how often do u change your tranny oil..

Some run down, my bikes 4 weeks old, Ive changed oil in it about 2 weeks ago? Maybe 1 week i forgot, changed tranny oil a few days ago. Havent changed the oil filter yet but Im probly changing the oil again after I install all my new stuff and putting in a new filter. Im using HP4M 10w40 and 80/85 honda tranny oil. Should I switch to the HP4S fully synthetic over the moly?

Mine will do it in neutral also. get your ride idling in Neutral and see if it still does it. If it's only happening in 5th gear there is another issue. Is your ride very throttle sensitive? Meaning does it stall easy from a stand still?

Yes, unless its been riden all day, it stalls alot. Not overly too much but more than id like.

But i dunno if its only in fifth..It does it in 4th too..ive never just nailed it in any other gear

there is a 1989 suzuki quadzilla for $2500 for sale i think close to u

Probably not the most reliable quad to get..considering its a 2 stroke and a 89..unless its in REALLY good condition..but you can never be too sure..but i could be wrong Sun could be really skilled at mechanical stuff. If its in decent condition id snatch that up..would be a blast!

Can you drill yamaha wheels to fit a honda bolt pattern? In theory i dont see anything wrong with it..other than you having more holes than normal..or would that make it weaker or something

The way I worked around it was just trial and error. If I open fast but smoothly instead of all at once it doesn't do it. That is the only time it does it right? Just when you romp on it.

Yes..like i said low fifth and i pinned it instantly..

I want to see the finalized pics!

I only know anything about them on trucks..but im sure thats different as ive never had a utility..and that information can easily be found on the internet..so no luck here sorry

broke a cv axle on a 2004 Suzuki Vinson 500... i wanted to know were can i find a cv axle for it.. and could i replace it with regular tools or will i need special tools? o and is it difficult to do without having that much mechanical experience.

After searching google..I couldnt find one..I would think your best bet would be either ordering one from suzuki..or your local suzuki dealer..usually they can get older parts..I know my honda dealership sells old parts for bikes..worth a try?

I highly doubt it is too..My friends says it will always do that pretty much..so imma just rejet and hope it goes away..Im so relieved

That's your jetting. Mine does that too. The reason being on mine is I have an after market pipe and that's all. When I slam the throttle open I'm dumping more exhaust out than I'm takin in air. So it almost acts like it floods for a quick second. What elevation do you ride at? From the factory it is jetted to run at sea level. If you would have explained it like that along time ago I would have answered right away. The info I just gave was from my mechanic. Get your carb dialed in with a jet kit and that will go away.

..Well chit..cuz im at sea level....My full pipe and jet kit is coming early next week. PLEASE let it be the jetting, could it be that somethings broken in the carb, or dirty or something? Cant see how never messed with it, whats the chances that its all factory jetting and it will be fixed once i rejet
