Heat and and a 1/2" drive impact with the coupler removal tool.

Is this a 61X single carb motor? A 9/15 Hooker should work well with your current setup and that pipe, the 10/16 might be too aggressive on a single carb motor. If you use the Type 4 on a TPE motor in the future, you will need to spend some time denting the type 4 (or any other dry pipe...

Has the effective RPM range of this pipe been established? If so, what RPM does this pipe make peak power at?

Any feedback on the performance of this pipe yet?

Are there more than 7 ports in the RR cylinders?

Here's an update on the +4mm 1021cc: My 144mm 17/22 C75 Skat-Trak impeller came in earlier this week so I pulled my Solas pump out and switched impellers again. Given our current air and water temperatures (high 30's to low 40's air and 40's water) I installed an adjustable valve on one of my...

I think you will be very happy with this setup!

Nope, I have to drive quite a ways further for mine.

-4.3 Carbon freak with another +4mm TPE 1021cc.

I had a chance to try the 964cc SS in the Aquabot this past Monday and I was very impressed with the power this motor makes (the aquabot handled very nice as well). The TPE 964cc is by far the most powerful SS motor I have ridden. My +4mm TPE 1021cc with Zack's light weight billet crank does...

Talk to Erik, tell him what parts you have or plan to use with your build and tell him exactly what you want your ski to do at the end of the day. He will provide you with the best information to make an educated purchase decision. You can also talk to Steve or Paul who are both also very...

I seem to remember being told by a reputable source that back when KHI was pouring big money into their factory race skis, they were using dry pipes that had the outer water jacket stampings welded to the expansion chambers along the entire weld seam, thus created two separate water jackets, one...

Here's an update on my 1021cc. I spent some time testing and tuning with my PET-2100DX this weekend. I'm currently running 125 Pilots, 132.5 Mains, 1.8 N&S, 80g Springs, 1/2 Turn out on high speed screws and 1 Turn out on low speed screws. My plugs are just starting to turn dark brown and the...

No video yet, I'll see if I can get something sometime this week.

Dave, Let me know if you need any help pressure testing the motor. I have a test plug that fits into the factory pipe coupler so you don't have to pull the entire exhaust system apart. I'll PM you my number. Eric.

I have a few other reduction nozzles I want to play with before I know which impeller/nozzle/pump cone combination I like best. What impeller are you running right now? Also, are you at 125P/130M for jetting in your 49mm Full Spectrums with your 964cc or something different? Eric.

I put 10 gallons of fuel through my 1021cc this afternoon. I can't believe the power this motor is making with pump gas compression and an MSD Enhancer! This motor is absolutely worth the wait! The power is very linear throughout the entire RPM range, yet at any point in the RPM range I can...

Check with Zack for current pricing and options but I paid around 1K with expedite shipping down to Erik. I weighed the complete long block (as pictured above) before I put it in my superjet last night and it came in at 82.8lbs. Out of curiosity I also weighed the 701 (also a complete long...

Ready to hit the water! We just ran out of daylight here though, so the ride report will come tomorrow.

I was told to leave a few things in my list for Christmas ideas by my significant other, so a real ignition will likely be added during our off season here in MN.
