Anyone have any experience with/own/bought/etc one of the MRP power packs? thoughts? Better or worse than getting an Airsal w/ a Technigas RS and a Malossi variator?
Thoughts, comments, etc would be appreciated. I would be getting it for my Vento Triton, but any experience with this would be appreciated, even on other makes and models.
Just curious about the quality and how the kit stands up to other parts from other manufacturers. Anyway, let the comments begin, and thanks!!

I bought an MRP Power Pack from Miami Moto. It came with the cast iron 70cc kit, 70cc pipe, OKO 21mm carb, racing clutch w/1500 & 2000 RPM springs, intake, reed block, reeds, 1500 RPM torque spring, racing variator, and roller weights. The odd part is that it was all packaged individually, not in the power pack box they show in pics, and I didn't recieve it all. I was missing the racing variator and rollers at first and after months of trying to get an email response or someone to answer a phone I finally got the variator sent out. It looked like cheap junk to me, and made me slower. Not so sure they didnt just send me any old variator. The MRP clutch broke witin a month or so. I never used the OKO carb, just used my stock carb. Big bore kit makes a nice improvement while still staying reliable. The MRP pipe is nice and will help you gain top end power. Havent used the intake because the reed block was cracked. As I said the variator I got, that prob wasnt actually MRP, was junk. Torque spring keeps it in the power band much better than stock. If I were going to do this over again, no way I'd buy the power pack. If my triton was stock again, I'd buy components separately and just get what I need. I would buy the MRP big bore again for a scoot that really gets used and you want to keep reliable for some time. I think the Airsal is just a little more performance oriented. It's a pretty popular choice, but I've heard people say it's not a quality kit... I think some people compare it to Polini, Malossi, etc... kits though and it's well below what they cost. I think its something like the MRP. I know my MRP pipe does its job, though it doesn' t really hit till high rpm with the MRP kit. Rallyrrr has a post about his Technigas pipe in this section. Malossi makes nice stuff, certainly ranking above MRP in my book. I would think their variator would be a good choice. If you part it out, I'd add in a 1500 and 2000 RPM torque spring and a set of 2000 rpm clutch springs for the stock clutch. MRP clutch beside stock clutch  MRP 1500 RPM torque spring by stock spring  MRP cylinder and stock cylinder  MRP big bore components and Wiseco needle bearing  Video of my Triton. I think it had the big bore, pipe, clutch, 1500 RPM torque spring, and 2000 rpm clutch springs here... (I'm 285 pounds, so keep that in mind. Smaller riders get to go faster.) That's how I ride most of the time and its reliable. I'm WOT on back roads a lot. |

Thanks for the tips. That really gives me a lot to think about. I had read somewhere that the cast iron cylinders would be more likely to seize than the aluminum would because of them not heating up as fast, and that you had to let them warm up longer. Have you heard this? Do you let yours warm up for a while before riding? How long?
Also, what year is your Triton? What size wrist pin (10 or 12mm) does yours take? Another thing, I am not actually finding MRP parts that specifically say they are for the Triton. Which cylinders and kits are you getting? One last question...do you know off hand how much it is just for the cylinder?
Thanks for the help and thanks for posting all the pics. It really is appreciated! BTW, is your avatar a pic of your actual bike? If so, it is nice! Do you have any more pics of it posted anywhere? What did you use to paint it? Ok, I'll stop asking questions now. Thanks!!

Have you heard this? Do you let yours warm up for a while before riding? How long? Before you worry too much about it, remember your stock cylinder is cast iron. Also, what year is your Triton? 2004 R4 What size wrist pin (10 or 12mm) does yours take? 12mm Another thing, I am not actually finding MRP parts that specifically say they are for the Triton. Which cylinders and kits are you getting? Cylinder kits for the air cooled Minarelli style engines work. One last question...do you know off hand how much it is just for the cylinder? You should be able to pick it up for just a bit over $100. Thanks for the help and thanks for posting all the pics. It really is appreciated! BTW, is your avatar a pic of your actual bike?

Glad I could help, and here's a link to more pics of my Triton... scootdawg.proboards59.com/index.cgi?board=pics&action=display&thread=7391 |

Thanks again for the help and for answering all of those questions! Right now I am thinking of getting a stage 1 kit from Provo because I can get the exhaust and variator I want (and it is a good price) and then if I want to do more in the furture, getting the MRP kit because of the reliability like you stated (I don't really race, I just go to work on it a lot (14 miles each way)). You also made a good point about how stock is cast iron. Of course I never thought of that. If I do get a cylinder, then I will at that time then consider a carb possibly too. The only thing I am unsure of is what I will do for a clutch. I get the feeling I will end up needing one. You didn't seem to like your MRP, right? Or did you say you didn't think it was actually MRP? I forget now. Guess I should go back to the original post! Oh, and thanks for the link to the other scooter pics! I have wanted to have a black scooter for a while (I kind of like flat black myself ) I wrote down the types of paint you said you used so that when the time comes I can look for it. Thanks again! |

Right now I am thinking of getting a stage 1 kit from Provo I have never dealt with Provo. I used to hang around there a little bit though, and all these posts would come up about never getting orders or any response from anyone at provo. The posts would then be locked or deleted. This was some time ago, perhaps they have changed. I personally will try to avoid them, and just wanted to put that out there. Perhaps do some research on them if you haven't already. Once again, I have no personal ordering experience there. Just my observations. The only thing I am unsure of is what I will do for a clutch. I get the feeling I will end up needing one. You didn't seem to like your MRP, right? Or did you say you didn't think it was actually MRP? I forget now. Guess I should go back to the original post! My MRP clutch got jacked up. It is no longer with us lol. I run the stocker with 2000 RPM springs now, and it works just fine for me. |
