From Pace quad to Race quad!

[Spywell]

Alright, for the next three weeks we will be keeping everyone updated with pictures etc. of a blasters transformation from slow to fast.

With the help of N8tsNastyBlasty and Rubbersalt we hope to show you how to take a slow blaster and make it fast.

Objectives:

• Take times of a stock 200cc blaster @ 120psi compression.
• Completely dissasemble atv
• Strengthen frame
• re-weld and extend a-arms
• new shocks with new geometry
• Port the engine
• increase compression
• build a fully custom 5 stage pipe to match the port job
• change the timing
• enlarged intake with larger reed cage
• shee hubs
• carb matched to porting
• high performance filter with custom outerwear

Through most of our objectives we will be taking and averaging times for every modification so you can see relative improvements throughout this experiment.

I will be updating this post if we add or subtract any objectives.

N8 will be in charge of porting/welding
Salt will give porting numbers/pipe design/welding/fabrication
I will be documenting/dissasembly/reassembly/riding/helping etc.

I hope we are able to create an exciting, informative thread, if anyone has an idea to add to our objectives list please tell.

Thanks!

This sounds like it will be interesting... I:I

 

[1995blaster]

would love some pics.

it looks more like a mission that a build hahaha i wanna c pics

At the same time, we are doing this AS CHEAP AS POSIBLE.

Basicaly, from our own pockets, we have $154 invested. That is including the blaster that is running.

Heres how we got the blaster; My dad bought an old 1978 honda XL250s dirt bike non running for $75. I adjusted valves and got it running. I purchased a front rim + tire for $60. I bought a new intake boot for $15. Then i bought $4 gas for it lol. Traded it outright for a non running blaster. Blaster needed a stator - N8 had a spare. Pet weiner was missing - I had a spare. Needle was missing inside the carb - was flooding over - N8 had a spare..

We are at $154 invested. I would like to keep the build under $300 total, but thats pushing the limits hard.. CR125 reeds alone are $15 >.<, Brakes are $20 >.< Chain and sprockets are I'm guessing around $40? Porting Bits are $15 or so. Seat cover materials maybe $10?

We like to do our own fabrication/work, so all we need are the parts we cant make

Stock pics are up, we would have gotten stock times today but it was well over 100 degrees. We have found a major intake air leak, hopefully we can fix her and get some times tomorrow!

It was hot hear to about 2 or 3 hours away. But Looks like you got a good project ahead of you guys. Btw i just restored my hood and tank cover you should do it with the blur i sanded it and then put on a few coats of mop n glo good stuff.

 

[Spywell]

Alright, we had a delay on getting our stock times. Apparently the loon who owned the blaster before us put the cylinder on without a gasket. We had some major air leaks around the base and head. I made a gasket for it and will try to assemble it within the next day or so. Sorry for the hold up, I thought the carb was just out of tune lol.

 

[1995blaster]

any updates? anything even done?

 

[Spywell]

any updates? anything even done?

Yea got the top end pulled, cleaned up, gasket made, head gasket annealed, carb tuned, removed a broken reed cage bolt, put it all back together and rode a stock blaster today.

Whoever owned this blaster before us had the head leaking for a long time and the base was leaking really bad since they didn't use a gasket or even silicone lol.

The stock carb is the biggest POS carb I have ever worked on in my life, it was a really bad decision on both Yamaha and Mikuni's part, I can't wait to replace the damned thing.

I guess it's true what they say, blasters are broken (slow) from factory, nobody around here has ever seen a stock blaster. It's surprising how slow they are, even more surprising how fast they can become! I do like the bottom end grunt of the stocker though, I can drift that thing all around. Then again, I can drift N8tsNastyBlasty around too Nathans blaster feels like a stock blaster x10 according to the ass dyno.

We will have slow times here real soon. I kept thinking that after I got this blaster put back together and running, I might not want to take it apart since I will have nothing to ride. After putting around on the stocker all day, I can hardly wait to tear into it, the things worthless stock! I don't mean to slam the blaster, but whoever rides a stock blaster sure don't know what they are missing, I hope to show them the light real soon!

i race a mostly stock blaster its got a 250r rear shock, +2 rear wheel spacers
nerfbars and a teather kill switch and im able to beat a 250 on grasstrack and mx !! u would be soprised how well it can handle when i push it hard, but dats my problem i have to dog the living sh1t on the quad to get the results im getting.

im probably getting some thing differant and the end of the year probably a gasgas if im not going into the 450 class. i could spend a tone of money to make it as quick as a gasgas but the cost of brembo brake and ohlins shocks, it would make more seance to get a gasgas 250 wild imo

There's always the handymans secret weapon...................duct tape lots and lots of duct tape

 

[Spywell]

We have the stock times and video BUT RubberSalt is holding them hostage, waiting on him to post them.

 

[tsean91]

You.get the times and video yet... Sounds interesting

 

[Spywell]

Wait, I was holding them hostage? You left the camera! I didn't even know I had it.. wher eis the video? You got the camera now.

These times might be a hair faster than stock - 68mm piston.

 

[Blaner]

good idea not panning out?

lets get some real facts and pics up chaps!--stop the jabbering, its been a month and i want to see this!

 

[Prime]

Pics and video please! I am very interested in this project.
