Mods began on the Venom X22R 250
 

The mods began on the Venom X22R 250 this morning. I started by stripping her down naked.:hehe: First was to remove the ehaust. Really easy once all the fairings were removed and that was easy also. I located the cat using a long stiff wire. Once located I used a cut off wheel on my grinder and cut around the cat. The cat itself was actually installed backwards according to the big flow arrow stamped on it. The cat came out easy compared to the one on my Hawk. I welded it back with my mig welder on the lowest setting so I wouldn't burn a hole through it. Anybody who has welded on this Chinese steel know exactly what I'm talking about. Lol after grinding the weld and painting I wrapped it with header wrap then reinstalled. I also had to grind the welds down inside the header pipe. Defiantly some restriction there. The bike comes with a good free flowing muffler so no need to replace it. Bike was no louder than it was before and still has that deep tone rumble.:D

More pics....

Congrats on cat removal, I wish I had a welder! I noticed today after one minute of running my TBR7, that the cat was glowing red. Is that normal?

The bike comes this a pz30 pumper carb which really has good throttle response. This carb didn't have the usual tamper proof screws but regular Phillips head. It came with a 98 main installed so I installed a 110 for starters. I didn't change the pilot as it was running fine with whatever was installed. The idle mixture screw did have the tamper proof cap so I drilled it out and actually came out with the drill bit. The idle mixture screw was barely open maybe 1/8 turn. I just set it 1 1/2 turns out from lightly seated. It started right up and idled smooth so didn't touch it. Later after I did all the other mods I took a little ride. Huge difference in throttle response and power. I'll have to change to a 115 main as it bogged a little around 7000 rpm's. Still need to break in before I beat on it. I did get up to 71mph briefly and wasn't full throttle. I'll have to check the accuracy with my GPS.

If you haven't tuned the carb yet it will glow red because it's running super lean from the factory.

After the carb tuning and replacing the plug with a NGK I installed the oil cooler while I had the fairing removed. I had plenty of room for the install unlike the Hawk which was kind of limited on space to install. I didn't take pictures but did take video that I'll post tomorrow or Monday. You can see the cooler in the previous picture I posted.

I also installed LED headlight while it was naked. I did have to take my rotary tool to make the hole a little larger to make them fit . so much brighter than stock. I installed my alarm then put all the fairings back on. I had a wedding to go to so I'll finish up the rest of the mods tomorrow. I did take the bike to go to the wedding.:D
Her she is all buttoned up ready to go.

A sportbike is a great way to arrive at a wedding.

I think the bike got more attention at the reception than the bride and groom. Lol

it really is a very nice looking bike!

Thanks, out all the colors I think the black looks the best. :thanks:

Congrats! Sweet ride, I am jealous! You have to do some speed testing when it is broken in I am so curious. 90 mph in the add!

I bit the bullet a few weeks ago and bought the Harbor Freight "Titanium" flux welder. It's routinely on sale for $170.


I'm not a complete muppet at metalwork; I can solder and braze quite well, and I have done a small amount of oxyacetylene welding but I have never worked with any kind of arc welder before. With no instruction other than what's in the manual and fooling around with it for an hour or two, I was able to jump right to patching a big-ass hole in the exhaust pipe of my friend's SSR dirt bike, and replacing the welded on nuts that hold the heat shield on. It weren't pretty, but it's holding.



The HF welder is definitely capable of doing exhaust work, especially if you don't care what the weld looks like! No gas, no tanks, no hoses, nothing to worry about with the flux core model. If you only use it twice a year (as it looks like I will) it'll be sitting on the shelf waiting for you when you need it, ready to rock and roll...

I wish he had broken it in BEFORE modding it to get baseline numbers.

Here's the automatic version. albeit not broken in. Interesting no shift revs direct drive it appears and seems to work pretty good.
