i got 2. ws7ii and s7. my s7 is gone now. needs new piston and sleeve but its been a while since i did the piston and sleeve. im getting a rb for my revo. im also going to try a ninja. the ninga will be my back up. go for a ws7iii or the new c6bb t7. the c6bb t7 looks good. im going to try it and sell the s7 i think.

I'm pretty sure they still make the S7 if I'm not wrong, or maybe it was the WS3 I saw in RCCA. But I have the TM523 and its a monster. Crazy power out of the box and I want to get it modded too and thats gotta have a nice affect on the power !

great motors hardly anny problems you dont need to change the glow plugs alot and they are fairley easy to tune plus they have tons of punch good luck

why you running a on road motor!!! lol.

i'm running a pair of C6's that were modded by powerhousercperformance.com and they are friggin nuts on power and i can get just over 10 mins. of run time @ 200deg. on exactly 125cc of fuel!! i have a ton of fuel though these and they are still tight as a motor will a gallon on them

you can't go wrong with rb,nova or o.s. engines

I bought it on impulse. i looked up the specs on the rb site and it's really similar to the S7 the only diff i found between the S7 and S7C is the S7C

-the carb opens to 9mm(not that i use the 9mm to crazy),
-the fuel consumption is less,
-the torque is less(not by much),
-has more power(by one bar),
-takes a Turbo glow plug
-and smaller cooling head.
-and the weight is 318gr

S7

-the carb opens to 8mm
-the fuel consumption is more
-the torque is more(not by much)
-has less power(not by much)
-takes a normal glow plug
-bigger cooling head
-and wthe weight is 356gr

All i need to do is get a bigger cooling head if i am going to race this in the summer. right now it runs great since the weather is cooler. when i raced, the average needle setting i was running is, 4 1/2 out on the HS and 5 1/4 on the LS. it ran great had lots of power and loads of torque and i was running an average of 225 to 250 F. SPEEDMETAL saw this engine run and said it ran amazing when he was helping me tune. all i need is a bigger cooling head and i am good. BTW do you know if you get the WS7lll head can you get on with the turbo conversion i already know the head would work since the parts number match just different cooling heads. What does anybody recommend on the cooling heads? any good name brands i should look at? let me know.

it's nuts on buggy to but i had to rich the crap out of it to run cooler and still runs amazing. if i get a bigger cooling head such as the ws7lll it would greatly reduce the problem and i could lean it out more to unlock it's true power. still when i raced had loads of power and torque compared to my GS R21PBX it makes look like a toy. btw what pipe did you run jordanak? i am running an ofna 086 pipe.

if your running that rich and still temping that hot in the winter......you will need a cooling head the size of a 2 story house to run that in summer in the offroad seen torqe is everything and also allows the motor to cooler and work less
