I want another to be back in stock!
Ib always get my items on time.
This thing is awesome! Very happy with the kit. Took less than two hours to assemble once it was painted. I’m 6’ 1” tall and it fits me perfectly!
The Tillotson 225 never disappoints. This is my second one. Paired with the juggernaut clutch. Make my drag racing tractor’s. Fly!!!! I will be purchasing another in the near future
This 225 is on my azusa Fram and it is perfect plenty of power!
I am quite happy with the service you guys have provided me with, and you've always answered my questions no matter how many questions I asked.
Paul has been a big help too, and he's always answered all my questions and emails. He did an amazing job with the engine, the power is amazing, and I even raced Motocross when I was younger, so I know about performance engines. I couldn't believe the output of the engine, it ran great, that was until it blew out the crank seal on the side cover, which really upset me and had me very disappointed, but thankfully Paul is going to fix it for me, which he didn't have to do, but this goes to show me how much GoPowerSports.com cares about their customers and that they are willing to stand behind their workmanship / Products, which will want me to do more business with you in the future!
I'm not sure why the seal gave out on the crank case cover, but it did, which shouldn't have happened, especially not with less than 2 hrs on the engine. Hopefully Paul can find out why it happened and prevent it from happening again, because I would really be upset and angry, not to mention disappointed if it were to happen again like it did this time, but let's hope that doesn't happen again.
You all are a great bunch of guys, and hopefully one day soon I'll be able to get down there to meet you all.
Thanks for everything, I definitely will keep recommending you to all my friends and family!
PS, Please get a front disc brake kit made for the Coleman CT200U-EX, because I definitely need one with all the power the engine has, my back brake pads heats up very quickly and is hard to stop!
This is the little engine that could. The Tillotson 225 is a monster and the throttle assembly I bought for the carb is much more responsive. I love it
Very nice drop in engine, works great, only one thing is that the plug (Autolite 3910x) that comes with it did quit working after 5-6 hours after first start. I recommend getting a NGK, will last for a while
Amazing my friends can’t keep up now lol
