Typhoon 90 motor work

[8d dad]

I am looking to get my son a typhoon 90. I am sure after some seat time we will want to do engine mods to it. I was looking on the Xtreme web page and saw that they offer a diff. high comp. head, cam as well as a 107 up grade. Has anyone done anything to theres? If so how have they worked?

[number52]

I have done this mod and it is a night and day difference compared to the one's I've sold that didn't have it. You won't be dissapointed.

[8d dad]

What mod did you do? A new cam? What cc motor 90 or 125?

[Spider 171]

Can you put this kit on the 125? I mean the 107? or the I believe 90cc Kit? to meet the 90cc rules class? Just wondering? I wonder if the 107 kit on a 125 will put out more power than the stock 125? Oh yeah has anyone come out with a fix for the clutch slipping? I think I should address that one before I add more power!

[number52]

The mod that was done is the 107cc kit that is offered directly from Xtreme.

Not sure if the cam will be different than what the 125 already has in it.

The clutch slipping? Are referring to the clutch not engaging when the shifter is held up or down so you can slip the clutch with the shifter rather than having to use a manual clutch. I am currently working on this problem!

[Spider 171]

I was referring to the clutch just slipping under power, 2nd, 3rd, especially 4th gear under any accelerration. I refer to this when I ride it, and with my son it is barely noticable in 3rd, but 4th is slipping under accelerration at speed not just putting around. We would like to get more power, but the auto-clutch set-up will not allow it. I am a little surprised on how long it is taking to find a fix, almost two-months in a week. I have heard there are alot of people trying to fix this issue so just a little surprised, I know it is a new machine that didn't have any testing so I am giving them the benifit of doubt. We just want the Quad to be right, not too much to ask for, I ordered it six months ago so We have been very patient!

[number52]

I haven't had this problem show up on any that I've sold. Are you sure that you have the clutch adjusted correctly? Should be all the way out and 1/8 to 1/4 turn in.

[ken ingram]

you need to change the clutch from a 4 clutch plate to a 5 clutch with HD spings
it worked for me!

[Spider 171]

It doesn't slip, how much time do you have on it? How is the shifting action with this set-up? Did Xtreme give this to you or did you get it elsewhere? Do you think it will handle extra power mods, like more hp?

[ken ingram]

so far so good . we have put alot of time on it and it works good.
parts came from xtreme.
i'm going to put a WRH head on it this weekend!!
well see if it can handle the billy holt power!!:D :macho

I installed a 16T front sprocket tonight and it made a world of difference. I bet it will run 50MPH now! May need to go down to a 15T if you run in some loose dirt though because I don't think 4th gear will be able to hold it. I only had a 16T off of my pit bike. I also cut the front bumper so it's behind the front tires and lightened the spring in the carburetor so it has an easier push on the thumb throttle.

[Spider 171]

I heard the sprockets would fit obviously but I wasn't sure if they were the same chain size, I thought they were 420, and the Typhoon is 428 right? Also I was told the rear was a pitbike sprocket as well, they both fit just want to make sure the proper chain size? .

they are two totally different engines the 90 is a honda clone and the 125 is a klx 110 clone

[Spider 171]

How sure are you about this info? Then the 110 mods should fit?

[OzLinc]

Close but no cigar......

The 90 is based on the Honda Z motor and the 125 is based on the Honda NICE. Main difference is cylinder hight (Z = 69mm) and the (NICE=78mm). That makes things hard.

From what can work out to get a 125 down in capacity you need a Jialing 110 3v crank, cylinder and head for a capacity of 107cc with a bore and stroke of 52.4 x 49.5.

And Spider....took my engine side cover off. Mine has a 5 plate already so that explains why I have had no slipping problems.

We convert our 125s to 5 plate clutches and HD springs...you need a new pres plate, hub, discs & plates...we are building approx 12hp with no slippage!

Still slips a bit with a 200 lbs. rider but works great with a kid riding. Keep in mind also that we are running it with a very agressive cam, 12.5/1 piston and full port and polish.

We have a HD 5 Plate Clutch kit for the Typhoon that will not slip at all even with Motor mods...the kit includes Clutch Hub, Pres. Plate, Lightweight Plates, Takegawa Discs, HD Springs, and Cover Gasket...works awesome!

[raidernut]

That mitchell kid out west is sure making it look awesome!!
