Backflip HP!! Assembling a Yamaha 62t Dasa 10mm big bore stroker. Building freestyle brap!

[@yeahok115sure]

I used Dasa ported Racing heads for all my yz250F. Dude is a scientist!!! His engineering is unreal! I’m almost positive he was the first person to do 5 axis CNC porting in the motocross industry

[@EricksonMachinePerformance]

Dan has been doing it forever!

Hey Mark, thanks for this vid man. I am building my 850ss Dasa next Tuesday and this is just perfect timing 👌 Love the vids mate Shaun 🇦🇺

[@EricksonMachinePerformance]

happy to help!

[@danielbecker6934]

Hi Mark, Thank you for uploading these vids and sharing your knowledge....so good....makes working on my ski a lot easier. Legend!

[@EricksonMachinePerformance]

Thanks for watching

[@rook761]

Do you have DASA power valves in stock??Japan

[@mxracingunlimitedltd7784]

A powervalve 2 stroke jet ski engine is the same as 2-stroke dirt bikes have had for a while for motocross style 85s, 125s, & 250cc's. Like a 2020 Yamaha YZ250X. Powervalve 250cc single cylinder 2-stroke reed engine, water cooling, and more stock.

[@EricksonMachinePerformance]

Yeah gas operated power valves aren't new. But when setup properly they can be a game changer!

[@mxracingunlimitedltd7784]

Great videos man!! I love them. Learmed a lottt of little tricks for my next rebuild/top end. Thanks for sharing!! If I want to have you build/assemble a motor for me or a customer, do you have a website? Jeff rebuilds the cranks. Who does the machine work? Thanks!

[@mickyjames9203]

Hey Mark great work as always.. I have a question for you im build 800 sxr engine 2005 would the torque settings be the same many thanks

[@matkeast4228]

Handy vid thanks mate. What piston squash to you normally run? I’m rebuilding my Dasa 950 8mm and unsure. Any advice welcome 👍

[@EricksonMachinePerformance]

Around .055" is normal. Can be from .035-.070"

[@korpcustom]

Hi Mark. As always love your videos. I just bought a dasa 1000 as well, with all kind of problems. One thing I don't know how to fix is that two of the pins in the crankcase that stops the bearings from spinning in the case is pushed all the way down in the case. Do you know a way to get them out. Thanks. Tommy andersen

email me your # [e-mail] ill be happy to help

[@michaelwall784]

Would you recommend removing the base gasket on a 61x 701 sj? I'm rebuilding the motor right now and curious what you think.

[@EricksonMachinePerformance]

NO

[@mxracingunlimitedltd7784]

What brand front and rear crank seals do you recommend? And where can i get oem for a fair price? Also what's the best website to order oem yamaha parts with best prices and availability?

[@dukenukembubblegum7311]

One little tip for when installing your o-rings is just get it on your fingers and pull the ring threw it. I work on monster cat equipment, and with the hundreds of o rings I put in that way seems to work well for me, and we use a stuff we call cat snot(basically the same shit, just cat recommended), but that shit is expensive so we try not to waste to much, plus it saves some time

[@EricksonMachinePerformance]

Yes but some heads the groove is oversized some you need more then just a light coat on the oring. I also rebuild, repair and remachine hydraulics for heavy equipment

[@EricksonMachinePerformance]

Thanks for watching!

[@ricardorabcross848]

Erickson , could you tell me where I can buy this piston

[@EricksonMachinePerformance]

Email me [e-mail]

[@puch7261]

Whats part numbers to rods-and domes? Website you order from.

[@EricksonMachinePerformance]

The rods are from Adr and the domes are Dasa if you need some feel free to email me [e-mail]

[@MomentumMindsetMaster]

Thinking about building a dasa for a freestyle so. Trying to shoot for around 1000cc, what are your thoughts on achieving 1000cc via more bore than stroke, more stroke than bore, or a happy medium? ... also without utilizing a billet case.

[@EricksonMachinePerformance]

That comes down to Budget. A 10 or 12 mm stroker with make more power then a stock stroke BUT cost way more $$$ most 1000cc motors have oem cases. Billet cases are mainly used on +1100cc engines that require 16mm or larger stroker cranks that can't fit in oem cases

[@EricksonMachinePerformance]

I have a 967 stock stroke video im doing now that will be posted shortly

[@jcsuperjet496]

Mark, Do most Power Valved Dasa Engines spec 20 ft-lbs for the Cylinder Head and 30 ft-lbs for the Cylinder Base? Example: Dasa 850 Stock Stroke Power Valved Engine?

[@EricksonMachinePerformance]

unless running crazy compression yes.

[@CleetSquad]

Flawless as always. You seen those c-clip guns?

[@EricksonMachinePerformance]

No i havent can you post a link id love to see but honestly i don't have much an issue with c clips but I love having new tools if they are worth it

[@alecduff8418]

Erickson Machine & Performance which Milwaukee tool you are using? How about the Milwaukee ratchet?

[@EricksonMachinePerformance]

@@sultanalmaazmi9661 I have a ton of milwaukee m12 and m18. The 2 in this video are the m12 3/8 stubby impact and the m18 1/2 high torque impact. I have the standard and fuel 1/4 and 3/8 ratchets as well. I love all of them!!!

Erickson Machine & Performance you are fully armed :) I wanna go for the fuel 1/4 and a ratchet for Jetskis Do you think it would be enough?
