I read a thread on here that said The 450r is hard to keep the front end on the ground and is almost impossible to ride with 2 people becasue the front end comes up all the time?? Is this true that they have that much power or not?
Also ive never adjusted valves myself and was wondering wat exactly do you have to do to adjust them?? always been scared to do it myself and costing me money but if you could tell me i would appriciate it Thanks in advance

 

The 450r will pop up sometimes not all...It has a good amount of power stock, but once you get used to the ride you can make it pull up or not once you can handle it...I have ridden mine with 2 people on it and it was fine, but I prefer riding people on my ds since it's bigger and has more torque...Well for the valves it isn't very hard to do, but you will need to pay attention to detail...You will need to put the piston at tdc first take the tank, plug, and valve cover off...You turn the engine over using a socket and wait til you see the tdc mark on the crankshaft, once that is established you know you are at tdc...Then take a feeler gauge and check for the valve clearances on both the intake and exhaust sides...if they are up to spec then you don't need to adjust them, but if they are off then you will need to loosen the cam chain tensioner,tie up the cam chain so it doesn't fall in the cavity of the engine, take off the decompressor, camshaft, and take the shims off of the valves...you will want to write down all the clearances and the size of old shims you have in order to figure out what size you will need to be putting back in...when you clean everything up and get the shims in you will want to put everything back in making sure it is torqued down to the right specs and the timing mark of the cam is still lined up and put the chain on and you will want to tighten the tensioner back up later on...also make sure the tdc mark is still lined up on the crankshaft...put the decompressor back in and check the valves clearances making sure they are back up to specs...then torque down the valve cover and you are set to go...That is just an overview of what you need to do just to give ya an idea and you will also need torque wrenches, micrometer or vernier caliper to measure the shim sizes, feeler gauge, assembly lube, locktite, I believe that is everything...anymore ?'s let me know

 

No offense guys, but 2 up on a 450r? The first thing I did to mine was go down 1 tooth on the front sprocket. This will help keep the front end down & in my opinion is easier to trail ride.The HRC kit is a must, makes a big difference.

 

why would you go 1 down for not wheeliing ?(SP) 1 tooth down would give you more low end power plus shorter gears and less top end. Which is much better for trails(from what I hear) if you want to keep the front end down go up a tooth or two. But your also going to have a hard time in the trails if thats where you ride. The 450r is already geared really high. You will have to ride the clutch way to much if your riding a stock 450 and going up a tooth.

Just my 2 cents

 

Thats def. not ture. I own an
05 450R and I ride with my brother on the back all the time beacuse he dosnt own a quad yet.
the only thing thats rough about the Rs are they DO NOT like to go slow. Dont get me wrong,
you can go slow thru trails as long as you have ur hand by that clutch at all times. As for wheeling
I can pull mine up 3rd gear doing a wheelie but you have to give it some pull. So the answer is no
its not close to impossible to have a passenger as long as you dont punch it from a roll or anything
you wont have much of a problem keeping it on the ground....hope this helps

 

Heavy 13 has it backward. Gearing down makes for more low end torque, and makes it wheelie more easily.

I have a 13 front sprocket on mine, and by no means is it wheelie happy. I can wheelie when I want, but I never have an unexpected wheelie and I sure don't have to fight to keep the front on the ground. As far as riding double, it's not designed for that so if you dump it over that's nobodies fault but your own.

 

Reconranger you are right. I had it backwards,it's been a couple since I changed mine.I checked my 05 & I went up 1.No offense to the 2 up riders but I don't think It's a good idea.

 

thanks
